Release version 0.3.1
Changelog:
- Important bugfix affecting ollection of activation statistics when retraining with BREVITAS_IGNORE_MISSING_KEYS=1. Statistics where not being collected and instead it was using the default baseline value of 1.0 to initialize the scale factor. The problem doesn't affect using load_state_dict(strict=False), which is an alternative to the flag above.
- Refactor proxies and mixins and simplify a bit the assumptions under which an injector proxy can be created (i.e. always within a quantized layer).
- Release tutorial on quantizers.
