This makes it possible to run spleeter without having to install pyton and pip on windows. See http://github.com/deezer/spleeter for more info on what spleeter is. Usage is `.\spleeter.cmd separate -p spleeter:5stems -o amen .\amenbrother.wav`

spleeter.cmd

@echo off & PowerShell -nologo -noprofile -noninteractive Invoke-Expression ('$args=(''%*'').split('' '');'+'$PSScriptRoot=(''%~dp0'');$env:GOLUWA_CURRENT_DIRECTORY=(''%cd%'');'+((Get-Content -Raw '%~dp0%~n0%~x0' ) -Replace '^.*goto :EOF')); & goto :EOF

# ^^^^^
# this is some magic to execute the rest of this cmd as powershell
# so we can run it from explorer with double click or cmd easily
