Add support for Android TV 6 & 7.0 (#350)

Adds support for Android TV 6.0 & 7.0 by reduce the min SDK to 23. Going
below 23 isn't practical since new releases of Jetpack libs require 23+.

Also includes some clean up for better gradle syncs & actually use the
datetime APIs available from desugaring on older versions.

Needs more testing before merge

Closes #341
