7543fd80e5 exr: check size of uncompressed buffer returned by uncompress()
The actual size of uncompressed buffer returned by uncompress() may be
smaller than expected, so abort decoding in such cases.

2c31ed3330 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.

f7985f348f 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.
