Do some code cleanup for RBTools.
Review Request #12128 — Created March 9, 2022 and submitted — Latest diff uploaded
This change cleans up some small issues across the RBTools codebase.
These fall into a few general categories:
- Remove unused imports
- Mark some regex patterns as raw strings to avoid invalid escape
- General style cleanup (blank lines, text width)
- Fix up a couple minor string type bugs.
Ran unit tests.
