onedrive-hook.lua

--[[
    Detects when a onedrive link is loaded and converts it to an absolute path to play the file.
    Uses powershell, so it only works on windows. Though if someone is using the cross-platform
    version of powershell, they may just need to change the first arguement from 'powershell' to 'pwsh'.

    Also includes script messages to add video/audio/sub tracks from onedrive:

    script-message onedrive/video-add [url] {flag}
    script-message onedrive/audio-add [url] {flag}
    script-message onedrive/sub-add [url] {flag}
