Consider adding material-components-android

[Jawnnypoo]

I am curious if KeepSafe would consider adding this component to https://github.com/material-components/material-components-android

I think this is a great material component and would serve nicely as an official component.

I feel like we would be glad to include it. It really depends on https://github.com/material-components/material-components-android/issues/2 being resolved first so I can see what is needed
