ENH: Add angle reindexing util functions, add example notebook

[kmuehlbauer]

Closes codecov/codecov-action#55

Todo:

• [x] add tests
• [x] replace old reindexing code with new functionality

[kmuehlbauer]

@mgrover1 I've added a notebook with an example use case. Would be great if you or others could test that with some fitting radar data.

~Codecov isn't getting the coverage right and does not point to the latest commit. Seems it wasn't uploaded at all. There is some discussion in the links below, how to handle that. Obviously codecov is getting rate limited every once in a while.~
