type annotation of PILBase.create

[jaidmin]

The PILBase.create method already can handle tensors, ndarrays and bytes in addition to a filename as input, but the type annotation only allows Path and str, so the typedispatch ignores everything else and returns the input.
Is there a reason for this?
I changed it locally and it worked just fine, am happy to create a PR to change this.

Ah that's a mistake on my side. Please do suggest a PR to fix this!
