Cleanup: Return combined return value from compressor id by name
Instead of returning the ID through a pointer and an error code as return status, return a single int that could be a compressor ID (positive values) or an error code (negative values). Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
