When using extractOne with score_cutoff, please return a (None, None, None) instead of None

This would simplify using extractOne for lists with items with no matches.

I will still need to think about this change. I understand this can be helpful when doing:

a, b, c = extractOne(...)

However it has a couple of disadvantages as well:

• different api than fuzzywuzzy/thefuzz
• breaking change in rapidfuzz (can not be changed before v3.0.0)
• makes other legitimate use cases harder:

if res := extractOne(...):
    a, b, c = res

In the long run I will probably guide people to this new API: #188
The final API is not clear yet, but this will likely raise a ValueError for an empty result, but allows the user to pass an initial value similar to numpy (https://numpy.org/doc/stable/reference/generated/numpy.amax.html#numpy.amax):

Compare(...).max() -> ValueError
Compare(...).max(initial=(None, 0, None)) -> (None, 0, None)

Thank you

I use :

a, b, c = extractOne(...) or (None, 0, None)

Speaking of that, i'm not sure it's a good idea to return None for the number in the middle.

[maxbachmann]

a, b, c = extractOne(...) or (None, 0, None)

Sounds like a good solution to @John-Schreiber's problem.
