✅ Add type tests covering all relevant datetime64 and timedelta64

[Aniketsy]

towards #417

tests includes :-

• datetime + timedelta
• datetime - timedelta
• datetime - datetime
• timedelta + timedelta
• timedelta - timedelta
• timedelta / timedelta
• timedelta % timedelta
• timedelta * int, / int, and reverse multiply ( i added this as per suggestion from llm)

please let me know if we need improvements in this or i've missed any test coverage .. ThankYou 😊

converting in draft, i'll fix these ci-failures.

#95 just saw this, i guess this could be the reason for ci-failure

for these tests as per my understanding we can add # type: ignore[assert-type] , but i think we can fix this issue @jorenham gentle-ping, please let me know if you have any pointers, i'll open PR for this issue shortly maybe (till mid-night 😁)

Fixing #95 is probably more difficult that you might think. You're of course welcome to try; but it can be pretty tricky to deal get all the type-checkers on the same page when dealing with Any.
If I remember correctly, I've already made this change in NumPy, but, numpy and numtype have very different ways of dealing with type promotions, so it wouldn't be a 1-to-1 translation.

thanks, i thought it would be simple, but as you mentioned its probably more difficult, i can give it try and reach out to you if i stuck or have any query, if that's fine ..
