i2c mutex module not installed during installation from GitHub

[jharris1993]

Installation target: Generic Buster image install from Raspberry Pi installation sources.

Additional information can be found at:
https://forum.dexterindustries.com/t/reprise-no-module-named-i2c-mutex/9957

Using either installation method, (Quick install, including sensors or the manual install method), attempting to run something using easygopigo returns the following errors:

Python 3.7.3 (/usr/bin/python3)
>>> %Run test_servos.py
Traceback (most recent call last):

    from I2C_mutex import Mutex
ModuleNotFoundError: No module named 'I2C_mutex'

How do I install this module?
Can it be included in the standard install process?
