smaller than expected, so abort decoding in such cases.

exr: make channel_offsets int instead of int8_t
...
Prior to this change max number of channels for float data which was
going to be correctly decoded was 32, which is rather small
considering that exr allows multiple channel layers.

exr: fix header parsing
...
the header in the sample provided for ticket #1306 is not parsed correctly and thus
ffmpeg tries to decode the sample instead of abording the decoding.
I tested it with two other exr samples I have - one float, one half float - and
they still decode correctly.
