Version 0.1.0

This version includes some minor changes I have been meaning for a while.

Changes:

PathPoint, while previously exposed, was not type hinted in the stub. It is now fully documented in the stub file. It also did not have x and y exposed which it does now
Travel did not have computed_path exposed even though it was documented as an attribute. It is a useful attribute so now it is exposed.
examples/readme.py now includes code for all generated images in the README rather than just the final example image.
Some println formatting changes were done to comply with newer versions of clippy.

examples/readme.py is now run by GitHub actions on commits to re-generate the README images so any changes are immediately reflected in example images.
A clear_extras method was added to Map to reset internal attributes that are set with things like with_obstacles. This allows easier re-usability of the same Map object rather than having to discard if you want to have obstacles shown at first and then removed.
