compress does not accept 16-bit input buffers

[aaron-boxer]

grk_compress_init rejects every component whose data_type is not GRK_INT_32.

Decompress can return GRK_INT_16, and signed samples up to 16 bits (unsigned up to 15) already fit in that buffer.

Accept GRK_INT_16 as compress input when the samples fit.

think you meant signed up to 15 bits and unsigned up to 16 ?

since GRK_INT_16 is signed, unsigned only stores up to 15 bits of storage, since negative number are not used. For signed, it uses the full 16 bits of storage.

okay, understand, it will switch to INT_32 for unsigned 16 bit
