Added Unity's new ProjectAuditor to the project

[BellringerQuinn]

Unity recently released a tool called "Project Auditor" in beta: https://github.com/Unity-Technologies/ProjectAuditor

The tool uses static analysis to look through the project and look for sub-optimal code, assets, etc. and produces a report for you.

It can be useful to get a high-level overview of how efficient our coding patterns are, how quickly our assemblies are compiling, etc.

Please keep in mind that the tool is very much in beta so we should take its feedback with a grain of salt.

To run it go to Window > Analysis > Project Auditor then start the analysis

Version Increment

Please ensure you have incremented the package version in the package.json as necessary.

• I have incremented the package.json according to semantic versioning
• No version increment is needed; the change does not impact SDK or Sample code/assets

Docs Checklist

Please ensure you have addressed documentation updates if needed as part of this PR:

• I have created a separate PR on the sequence docs repository for documentation updates: Link to docs PR
• No documentation update is needed for this change.
