⚡ Use Rust to Save JSON files

[hannah275]

This work focuses on converting code in tiatoolbox/utils/misc.py and tiatoolbox/models/engine/multi_task_segmentor.py from Python to Rust with the aim of reducing the time it takes to run the code. This Jupyter notebook shows the speedup that certain functions are having when written in Rust.

Issues:
-If the number of bytes needed goes above 32 an error would occur
-Currently test_rust.py is running during the Python and Rust tests
