Update to androidx

[eygraber]

Is there anything blocking updating this library to use androidx? I could make a PR if you would accept it.

I would love to use the library, but my policy is to not turn on Jetifier anymore, as androidx has been out for a while.

Hi @eygraber. There's still a lot of projects who use AppCompat and moving to androidx might not be as possible or trivial as one would think. That's why I would like to provide this component as stable and complete as possible before moving to androidx.

PR are welcome. Please feel free to contribute as much as possible.

There's still a few functionalities I would like to implement in this component before moving to androidx.

@tiper checking in on this since it's been a long time since the previous answer, and this is the last dependency I have that is preventing me from turning off Jetifier. Any thoughts on migrating this library to AndroidX? I'd definitely prefer that to changing libraries, and it also feels like a change that's now past due if this library is still being maintained.

Edit: It actually looks like this fork may have completed the necessary work: https://github.com/thiago-you/material-spinner
