Support “Reuse[Dep1] | Dep2”

[Gallaecio]

e.g.

request_or_response_url: Reuse[ResponseUrl] | RequestUrl

Should use RequestUrl unless ResponseUrl is also requested separately.

I run into a fundamental issue that I was not expecting:

>>> from andi.andi import Reuse
>>> class A:
...   pass
... 
>>> class B:
...  pass
... 
>>> Reuse[A] | B == B | Reuse[A]
True

From the docs:

When comparing unions, the order is ignored

Should I try to find a work around that? Maybe a different syntax? (e.g. Reuse[A, B], or Reuse[A, 0] | Reuse[B, 1] | C)
Should we only support 1 reuse per dependency (i.e. no support for Reuse[A] | Reuse[B] | C), and assume that even in A | Reuse[B] we should prioritize B if it can be reused, even if A comes first?
