v0.0.3

Bug fixes:

• The assets on PyPi were not displayed so they were converted to hyperlinks in the README
• MapType.Hidden would not reveal the current position in a path

Changes:

• Dots, obstacles and the grid now take priority over the path pixels instead of being drawn before the path was applied.
• Added a bunch more tests and added workaround for issue with half transparent pixels for tests
• Removed the code that replaced references to images in the README for readthedocs as they are hyperlinks now
• Added code that generates the example before the steps for the example
• Added a bunch of potential errors to Travel::new/Travel.__init__ for various scenarios

The main thing missing before a v0.1.0 release is duplicated attributes in the readthedocs documentation which I am still figuring out how to get rid of. Better enum support for stub files would also be useful, waiting on Jij-Inc/pyo3-stub-gen#86.
