Specify key type of EdgeSettings.qn_domains and NodeSettings.qn_domains

[redeboer]

The key of qn_domains in NodeSettings and EdgeSettings can be typed with an alias like EdgeQuantumNumber instead of Any, see #278 (comment)). So the type would be something like:

EdgeQuantumNumberType = Union[
    type[EdgeQuantumNumbers.pid],
    type[EdgeQuantumNumbers.mass],
    type[EdgeQuantumNumbers.width],
    ...
    type[EdgeQuantumNumbers.g_parity],
]
NodeQuantumNumberType = Union[
    type[NodeQuantumNumbers.l_magnitude],
    ...
]

As an aside: all of this indicates that the decision to type everything with complicated NewType classes etc was a bad one. Issues like #280 suggest typing everything with TypedDict instead (so based on the name of the key rather than the key type itself).

Has been implemented in the remove_spin-projections_in_cons-rules-branch. Issue should be closeable after merging.

We'll have to do a bit more probably ;) There are a lot of places where Any should be replaced with EdgeQuantumNumberType/NodeQuantumNumberType.

Btw, for lower Python <3.9, use from typing import Type instead of type.
