Fix aperture photometry bug for cubes in deconfigged

[MatthewPortman]

Description

This pull request is to address an error that occurs when aperture photometry is attempted on cubes in deconfigged. The issue was that several of the checks in the code were hardcoded to imviz and cubeviz but were not updated with the introduction of cube loaders. Those checks were updated throughout the code (mostly to dimensionality checks).

should this also be for images (not cubes) in deconfigged or no (because deconfigged has unit-conversion and imviz does not)?

[MatthewPortman]

Oo yeah good catch, do you think a dim check is enough?

[cshanahan1]

this tolerance seems pretty low, did something change so doesn't match as well anymore?

[MatthewPortman]

At some point in my testing, deconfigged was returning a slightly different value than cubeviz (on the order of 1e-3 I think) so I added the allclose. But I just tested again with the old exact value and it works so I'll revert that!
