* New indexes for states table
* Added recorder_runs indexes
* Created a new function for compound indexes.
A new function was created because it makes it a little cleaner when creating
a single-field index since one doesn't have to create a list. This is mostly
when creating the name of the index so with a bit more logic it's possible
to combine it into one function. Given how often migration changes are run,
I thought that code bloat was probably a worthy trade-off for now.
* Adjusted indexes, POC for ref indexes by name.
* Corrected lint errors
* Fixed pydocstyle error
* Moved create_index function outside apply_update
* Moved to single line (just barely)
