iPad Pro 12.9 (2021 / M1) + PleX - Sync'ing 4K HVEC / H.265 content without transcoding

iOS.xml

<?xml version="1.0" encoding="utf-8"?>
<Client name="iOS">
  <!-- 
    Description: Allows sync'ing / downloading any PleX content, including 4K HVEC HDR10 content, to the iPad Pro 12.9 with M1 chip.
    Author: Quentin Machu (https://github.com/Quentin-M)
    Disclaimer: There might be a few combinations of unplayable content as I haven't tested rigorously, but that ain't my goal today.
    Instructions: Replace iOS.xml in /usr/lib/plexmediaserver/Resources/Profiles/ (or use /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Profiles), profit $$$ while the battery lasts (if it does).
