macos plist for remapping caps lock to left control, and right control to Fn which you can't do in system settings

com.local.KeyRemapping.plist

<!--
Generated with: https://hidutil-generator.netlify.app/
Put in new file: ~/Library/LaunchAgents/com.local.KeyRemapping.plist

load with:
$ launchctl load ~/Library/LaunchAgents/com.local.KeyRemapping.plist
unload with (if you change it):
$ launchctl unload ~/Library/LaunchAgents/com.local.KeyRemapping.plist

should preserve through reboots.

I did this because I needed a Fn key on my external non-mac keyboard because
 I use yabai (github.com/koekeishiya/yabai) for window management on macos, and the Fn key
 works as a mouse modifier to drag around windows. I also prefer the caps_lock button 
 to be control, but if you do this in system settings/modifier keys,
 it sets caps_lock to right_control, which would then get re-mapped here to Fn.
