Release 0.7.5 (#70)

* Resolve issue with opaque tokens not being parsed correctly * Increase test coverage * Further improvements to test coverage and code quality * Add new providers. * fixup! Add new providers. * Cleanup. * fixup! Cleanup. * fixup! fixup! Cleanup. * fixup! fixup! fixup! Cleanup. * fixup! fixup! fixup! fixup! Cleanup. * Memory management optimisation 24 bytes per Put < 256-4096 bytes per buffer allocation avoided (10-170x difference) * Pooling cleanup.
