Oblique illumination reconstructions

[talonchandler]

This PR adds multi-aperture oblique illumination reconstructions to waveorder.

A single new parameter illumination_sector_angles enables these reconstructions, best described by example:

1. illumination_sector_angles = None uses the old behavior---a single circular illumination aperture
2. illumination_sector_angles = [(0, 45), (45, 90)] reconstructs from two sector-illumination channels, the first sector from 0-45 degrees and the second from 45-90 degrees.
3. illumination_sector_angles = [(i * sector_angle, (i + 1) * sector_angle) for i in range(8)] + [(0, 360)] reconstructs from 8 sector-illumination channels and a final full-aperture channel.

Below is a simulation of a sphere (first column) and simulated data acquired under different illumination orientation (second column). As expected, the reconstruction with a single full aperture (third column) is not as sharp as the reconstruction with all 9 channels (last column).

The tests are passing, but this isn't quite ready for review + merge until after the 3.0.0 release.

Oblique reconstructions require CZYX arrays (instead of the current ZYX arrays), which means introducing a backwards incompatible change to the API. Let's review and merge this after 3.0.0.
