Add debug functions to log parsed parameter set and header content. (#19)

* rocDecode/HEVC parsing: Implemented correct logic to set active VPS, SPS and PPS: start from slice header and up. Added video image size change detection. Fixed slice_segment_address bits calculation in slice segment header parsing.

* rocDecode/HEVC: Changed variable naming to Google style.

* rocDecode/HEVC: Added VPS, SPS, PPS, and slice segment header content logging functions for debug purposes.

* rocDecode/HEVC: Compacted opening bracket lines to keep coding style consistency.
