If able to get the ext info, show J2K codestream lossiness type. Otherwise, throw a warning, but continue on since it shouldn't affect the ability to decode.
If a lossless cstream is requested, quantization isn't needed. Notify the user that quality is ignored when :lossless selected.

Hi there @MartinPulec!
Submitting this PR to make a few additional changes to cmpto_j2k vcomp/vdec:
vdec/cmpto_j2k
cmpto_j2k_dec_cstream_get_ext_img_infoto get lossiness information from the cstream while probing the internal format. If successful, print the image lossiness type. Otherwise, warn the user that the query was unsuccessful and continue since this does not affect the decoder's ability to decode an image.vcomp/cmpto_j2k
:losslessis requested, only callcmpto_j2k_enc_cfg_set_losslesssince quantization is ignored in the case of a lossless compression. Otherwise, callcmpto_j2k_enc_cfg_set_quantization.:lossless.:quality=#is ignored when:losslessis used.
