Support integer types in flag arrays

[sjperkins]

• Closes Flag format: uint8 vs bool #346

If I recall correctly integer FLAGs were an SKAO use case whereby different bits represented different flag categories. This is somewhat analagous to MSv2 FLAG_CATEGORY.

Signed integer types didn't seem appropriate so they have been left out.

Yes, I've updated the original comment.

Pull Request Overview

This PR extends the flag array data types to support unsigned integer types in addition to boolean values. This enables the use of flag arrays where different bits represent different flag categories, similar to the MSv2 FLAG_CATEGORY concept.

• Extended FlagArray type annotation to include numpy unsigned integer types (uint8, uint16, uint32, uint64)
• Updated JSON schemas for both VisibilityXds and SpectrumXds to support the corresponding numpy dtypes

Have been pushing to origin rather than my fork, which has been confusing for github actions. I think it make sense to favour changes made on my fork.

I think I've cancelled most of the superfluous actions (still getting used to he amount of runners and time this takes), but I'll bump this PR tomorrow morning GMT+2 once #477 has finished running
