Subject: [PATCH 1/2] add `Axis::devices` to get all the input devices

technically a web edit, but i did the changes locally and it worked fine, i'm just too lazy to figure out how to make a pull request from not the web thing

the test is probably not needed but this feels like something that wouldn't error if the implementation were to change
