Windows support

[souvikinator]

For lsx to work in windows, on needs to port install.sh and lsx.sh to powershell script.

You probably might want to use batch for this, if possible, because PowerShell by default disallows script execution. It's really wild

[zQueal]

Little bit bigger than that. lsx compiles just fine for windows, but there's a persistent error regardless of input;

lsx error: some error occured
 list size -3 must be greater than 0

But most other commands work fine;

❯ lsx set-alias -p "C:/Users/zqueal/Downloads" -n downloads
INFO: done

But they won't work;

  Users 
❯ lsx downloads
