Version lock files with requirements.txt

[isaiah-harville]

Closes #334

[isaiah-harville]

Requirements are changed/added/removed in requirements.in and the locked requirements.txt file is regenerated with:
pip-compile requirements.in in Python v3.10. As a rule of thumb, generate these files with the lowest supported python version. The pip-compile command is found in the pip-tools python package.

Lots of benefits to this, especially for the docker image building process. It is usually preferred to copy over the requirements.txt file into the image and pip install requirements that way.

Unfortunately, it looks like I don't have permission to assign any reviewers.

I've got it set to merge into 1.1.0-dev. I need to test it, then I can approve a merge. Thanks @IsaiahHarvi !
