doubletake crashing android tv with first party apple airplay app

[NyaomiDEV]

When I connect, upon PIN entering, the AirPlay section on the TV crashes and doubletake never connects.

It looks like a couple other people have also encountered this behavior and taken a stab at fixing it (see #1 and #2). For non-Apple devices (some Samsung and Fire TVs) that report "Airplay 2" support it appears that they simply skip the Fairplay handshake, which isn't supported right now but should be a straight-forward fix.

I don't have a way of testing this locally, but just ordered a Roku device that reports support for this feature so should be able to have something for you to test soon ™️.

Should be fixed with 309ce0c.

I tested today with the git tip, and my TV seems to still crash...
