In using libdvbv5 to read off-air EIT (UK freeview), I find that to read
the full schedule one needs to rrad tables with TIDs 0x50 to
(potentially) 0x5f. However in descriptors.c only table 0x50 is given an
initialiser function, and so 0x51 onwards cannot be read as it stands.
Therefore I have made a small change to descriptors.c (attached) to to
add initialisers for 0x51-0x5f (and actually 0x60-0x6f). I have not used
the latter, but the former certainly allows me to read all future
events, whereas with 0x50 alone, could only read 3 days.
