feat: add precincts reporting percent override

[chriszs]

Description

This PR adds an override to allow specifying a reporting status for precincts in a specific county. To use, you add --precinctsReportingPct='{"bacon":0}', specifying the county IDs and reporting percents, to the CLI. This sets all the subunits to the same reporting percent, as well as overall result, so the above example will set all subunits in Bacon county to 0 as well as the overall percent for Bacon county itself.

[lennybronner]

why does the test use a fixture and not an actual page? also, can we add a unit test for this?

[chriszs]

@lennybronner No particular reason, it's just better to use a fixture than have your test hit a live API. Yes, we can add a unit test using that same fixture.

[chriszs]

Unit test added.

Why does expected votes go away when we override?

[chriszs]

@lennybronner Expected votes only appears when the precinct is fully reporting. It is set to the turnout.
