Added

• Support for unpickling torch BFloat16Storage (PyTorch bfloat16 values are converted to Go float32).

Changed

• Performance improvements (mostly involving better buffered reading, and new default capacities for maps and slices)
• types.Dict is now implemented as a slice of DictEntry, rather than a slice of pointers to it, to reduce extra allocations.
• Test data has been regenerated with Python 3.10.9 and PyTorch 1.13.1.
