Stream bindings are slow and broken

[jonathanunderwood]

The streaming bindings are currently flagged as experimental and are not built by default. The problems with these bindings include:

• The test suite fails on windows (64 bit) and Aarch64 architectures
• The test suite takes too long to run hindering development
• Decompression performance is terrible (#218)
• Ring buffer is not implemented (#187)

Overall the design of these bindings and their test suite needs revisiting. An approach to consider:

• Provide bindings in the extension module for the API bindings, but not the double buffer and ring buffer implementations
• Implement double buffer and ring buffer functionality at the Python layer
• Drastically reduce the set of test cases
