The number of components is given only by TIFFTAG_SAMPLESPERPIXEL / tiSpp.
Querying TIFFTAG_EXTRASAMPLES only give information about which channel is
the alpha channel, but we mostly ignore it for now, so remove that part of the

Partial revert BPC related check of #975 ( #979 )
...
PR #975 introduced a check that rejects images that have different bit depth/sign
per compoment in SIZ marker if the JP2 IHDR box has BPC != 255
This didn't work properly if decoding a .j2k file since the new bit added in
opj_cp_t wasn't initialized to the right value.
For clarity, tThis new bit has also been renamed to allow_different_bit_depth_sign
But looking closer at the code, it seems we were already tolerant to inconsistencies.
For example we parsed a JP2 BPCC box even if BPC != 255 (just a warning is emitted)
So failing hard in opj_j2k_read_siz() wouldn't be very inconsistent, and that
alone cannot protect against other issues, so just emit a warning if BPC != 255
and the SIZ marker contains different bit depth/sign per component.
Note: we could also check that the content of JP2 BPCC box is consistant with the one
of the SIZ marker.
