Adds VM Partition and Formatting Script

This script will help create a VM with the following attributes:
1. BTRFS file system with subvolume creation and mounting.
2. LUKS2 Full Disk Encryption.

Additional commands and comments will be added when `flake.nix` is implemented with the proper structures.
At the moment I just want to provide an MVP that helps people contribute to [Sublinks](https://github.com/sublinks).

+### Partitioning: Stage Start.
+
+## Creating a GPT partition table for our reproducible dev environment.
+sudo parted /dev/vda -- mklabel gpt
+## Configuring a boot partition of size 525 MiB with a 1MiB offset.
+sudo parted /dev/vda -- mkpart ESP fat32 1MiB 526MiB
+## Setting the first partition as our boot location.
+sudo parted /dev/vda -- set 1 esp on
+## Creating a primary partition that allocates/uses the remaining space (starting from our boot to leaving 16GiB for swap partition).
+sudo parted /dev/vda -- mkpart primary 526MiB -16GiB
+## Allocating the remaining 16GiB of disk space for a swap partition.
+sudo parted /dev/vda -- mkpart linux-swap -16GiB 100%
+
+### Partitioning: Stage End.
+
+
+
+### Format Stage 1.
+## Formatting the boot partition with the FAT32 file system.
+sudo mkfs.fat -F 32 -n BOOT /dev/vda1
+
+
+## Initializing the swap partition.
+sudo mkswap /dev/vda3
+## Activating swap.
+sudo swapon /dev/vda3
+
+
+### Full Disk Encryption: Stage Start.
+## This FDE stage can be skipped/commented if you don't need/care about:
+## [Encryption at Rest](https://www.youtube.com/watch?v=5rlZtasM-Pk).
+## [Data at rest - Encryption](https://en.wikipedia.org/wiki/Data_at_rest#Encryption).
+
+## All of the options/flags are succinctly described on the [Archlinux Wiki Site](https://wiki.archlinux.org/title/Dm-crypt/Device_encryption#Encryption_options_with_dm-crypt) (please donate if you can!<3)
+## Fully encrypts the main storage space using LUKS2 with the [Argon2id key derivation](https://en.wikipedia.org/wiki/Argon2).
+sudo cryptsetup --verbose --type luks2 --cipher aes-xts-plain64 --hash sha512 --key-size 512 --pbkdf argon2id --use-urandom --verify-passphrase luksFormat /dev/vda2
+
+## Opens the encryption while also labeling the disk partition to "luksroot".
+sudo cryptsetup luksOpen /dev/vda2 luksroot
+
+### Full disk encryption: Stage End.
+
+
+
+### Format Stage 2.
+## If FDE was skipped please uncomment and use the "Alt" variant bash commands and comment out the "First" commands.
+## First:
+sudo mkfs.btrfs -L nixos /dev/mapper/luksroot
+## Alt:
+# sudo mkfs.btrfs -L nixos /dev/vda2
+
+
+
+### BTRFS Subvolume Creation: Stage Start.
+## First:
+sudo mount /dev/mapper/luksroot /mnt
+## Alt:
+# sudo mount /dev/vda2 /mnt
+cd /mnt
+sudo btrfs subvolume create /mnt/root
+sudo btrfs subvolume create /mnt/home
+sudo btrfs subvolume create /mnt/nix
+sudo btrfs subvolume create /mnt/.logs
+sudo btrfs subvolume create /mnt/.snapshots
+cd
+sudo umount /mnt
+
+## First:
+sudo mount -o compress=zstd,discard=async,noatime,space_cache=v2,subvol=root /dev/mapper/luksroot /mnt
+# Alt:
+# sudo mount -o compress=zstd,discard=async,noatime,space_cache=v2,subvol=root /dev/vda2 /mnt
+
+### BTRFS Subvolume Creation: Stage End.
+
+
+
+### Partition Mounting: Stage Start.
+## Creating the corresponding directories to mount the subvolumes.
+sudo mkdir -p /mnt/{boot,home,nix,.logs,.snapshots}
+
+sudo mount -o compress=zstd,discard=async,noatime,space_cache=v2,subvol=home /dev/mapper/luksroot /mnt/home
+
+sudo mount -o compress=zstd,discard=async,noatime,space_cache=v2,subvol=nix /dev/mapper/luksroot /mnt/nix

+
+sudo mount -o umask=077 /dev/vda1 /mnt/boot
+
+### Partition Mounting: Stage End.
+
+
+
+### Initial Config Generation.
+## This generates the initial `configuration.nix` and `hardware-configuration.nix`.
+## `configuration.nix` will be replaced with the one provided in the repository but the command is still necessary to generate the proper config for `hardware-configuration.nix`.
+sudo nixos-generate-config --root /mnt
+
+
+
+
+# sudo nixos-install --no-root-passwd
+## ^this last bash command is commented to allow users to configure/customize their dev environment before performing the first install.
+## Once you've added your username, password, and a hostname into `secrets.nix` you're ready to install!
+## Running this command will perform the first NixOS install using the config details that was provided in:
+## `configuration.nix`, `hardware-configuration.nix`, `secrets.nix`.
+
+
+## After the initial install is complete, you'll want to use/run the following command to update your system:
+# sudo nixos-rebuild switch --upgrade
+
+## ^this updates your system on the fly and generates a new bootable entry when you first turn on your computer/VM.
+## Congrats you now have an indestructable system!
+## Whenever one entry/version fails to boot, 
+## you can restart your comp and just select another previous version and choose to update again.
+
+
+## Ex: version 1 works but you decide today's a good day to update. Version 2 loads on the fly, you work for a bit, turn off your comp, and turn in for the day.
+## Later, after turning on your comp and loading v2 it fails to load which sucks.
+## So you load v1 again, log in, update again which creates v3.
+## If v3 works then your update just works and the broken v2 update can safely be nuked from orbit.
+## ez upgrades, ez life
