Add timefree availability check

afaict nhk doesn't have timefree, and it says as much on the programme pages

The download doesn't fail though, you just get a loop of elevator music
and an apology that it's not available (lasting the duration of the programme)

from tsDetail.js
tsInNg = playable in the area
tsOutNg = playable outside the area
(maybe - just a guess really, but seems to line up)

outside station area + playable in area + not playable outside = not available in your area
outside station area + not playable in area + not playable outside area = not available on timefree
inside station area + not playable in area = not available on timefree

we'll always be in the station area, so we only have to check tsInNg

included a message about NHK Radiru because so far i've only seen NHK programmes
be unavailable

one day i should make the programme_meta func return a dict or something
instead of just adding stuff on the end ad infinitum
