Initial setup

[haberdashPI]

This defines two functions that are handy for computing joins over time spans:

• interval_join and
• groupby_interval_join

Rows match in this join if their time spans overlap.

There is also a simple utility function (quantile_windows) for joining over regularly spaces intervals.

Remaining actions:

• [ ] Close https://github.com/invenia/Intervals.jl/pull/193, so we can use my newly created find_intersections function from that repo.
• [ ] Remove Manifest.toml entries from this repo and verify that CI now works.
• [x] Add JuliaFormatter / reviewdog setup

Will be releasing this as a 0.0.1 release, and add a 0.1.0 release once https://github.com/invenia/Intervals.jl/pull/193 merges.

Note that one of Phillip's comments was resolved but is still applicable. Also, it would be good to fix the formatting issues and set up reviewdog + JuliaFormatter.

Is this the comment about the authorship that I missed above?
