Optimize Harfbuzz-Pure.
Fix segfaults & include test assets (major refactor).
Add documentation & corrected type signatures.
Add, test, & fix shaping function.
Fix build linking errors (mostly by upgrading GHC). I'm now running on this on elementary OS Jolnir.
Try wrapping HarfBuzz C++ functions in C functions for calling convention/linking issues. Committing so I can try building on a newer OS.
Implement conversion from functional Buffers to imperative Buffers.
