Add support for Arlec RF transmitter.

Issue #1516

Since this supports learning 8 remotes with 8 buttons each, there were
too many buttons to expose as buttons, so each remote is exposed as a
select entity with 8 buttons as options.

This is less convenient in the UI than buttons, but should be easier
for automations.
