NixOS should be able to support the Nintendo Switch Pro controller for
steam and non-steam at the same time. Currently there are two mutually
exclusive ways to support the Pro Controller: Steam and `hid-nintendo`.
Unfortunately these don't work together, but there's a workaround in
newer versions of `joycond` (described [here](https://wiki.archlinux.org/title/Gamepad#Using_hid-nintendo_pro_controller_with_Steam_Games_(with_joycond))). To use this
workaround `hid-nintendo` and `joycond` need to be updated, and the
systemd and udev configuration needs to be made available in NixOS.
