.SYNOPSIS
    A chdman wrapper written as a Powershell/pwsh module. Tested on Powershell Core 7 only.

.DESCRIPTION
    Compress a single file or entire folder into .chd format. Useful for easily compressing multiple files/formats supported by chdman into a more useable single-file type.

.PARAMETERS
    $SourcePath (where your file or folder is located currently on your disk with .bin/.cue/.gdi), $DestinationPath (folder where the output will be saved).

.SETUP
    1. Download and ensure chdman works on your windows path. It can go into any of the folders listed under this command:
        $env:path -split ";"
    2. Identify your user module folder for Powershell: 
        Write-Host "Place this module in: $($env:PSModulePath -split ";" | ? {$_ -match "documents" })" -ForegroundColor Green
    3. Create a new folder in the Powershell module folder found above named "Compress-CHD".
    4. Add Compress-CHD.psm1 to the new Compress-CHD folder.
    5. Add Compress-CHD.psd1 to the new Compress-CHD folder
    6. Reload your shell environment using the below command, and enjoy!
        Get-Process -Id $PID | Select-Object -ExpandProperty Path | ForEach-Object { Invoke-Command { & "$_" } -NoNewScope }

.EXAMPLES
    Compress-CHD -SourcePath "C:\ROMs\Saturn" -DestinationPath "C:\chd_out"

        [string]$DestinationPath
    )

    Write-Host "Starting CHD Compression: $($SourcePath) -> $($DestinationPath)"

    # Get all *.cue, *.gdi, *.iso
