Add precision reducer classes along with associated and dependent classes and tests

[badger3512]

• Added Classes:
  • GeometryPrecisionReducer
  • PrecisionReducerTransformer
  • PointwisePrecisionReducerTransformer
• Migrated the overlayng directory as dependency classes for the above
• Modified 20 additional files to integrate the changes

A total of 54 files were added/modified. I hope I didn't break anything.

Hi @badger3512 , thanks for this nice big chunk! I will check it out in the next few days. One question. Did you port from the latest jts master and adapt the necessary code here in the dart version?

Hi @badger3512 , thanks to your PR, I decided to add a test run github action to the repo, which now should be working.
Would you be so kind to merge in that change into this branch to see if the tests are properly run? That would be amazing from you, thanks.
