This PR adds support for a lossy mode in Btune. To use it, blosc2-grok will have to be installed in the system. Furthermore it can only be used when compressing images which datatype are integers.
The way this mode works internally is by a combination of neural network and heuristic results.
Because we cannot compute on the fly the quality loss, the has_improved function and score function will only take into account the ratio and speed tradeoffs and the compressed bytes and compression time or decompression time.
