Overflow Error on returnMask

[Jomithy]

Hello,

When running find_maxima.ipynb, I encountered OverflowError: Python int too large to convert to C long traced back to:

y = pListy[0:listlen].astype(np.int32)

-->types[y,x] &= resetMask

types[y,x] |= PROCESSED

Downgrading to numpy 1.26.4 from 2.3.3 temporarily fixed to issue, so it seems like the error is due to stricter type handling in bitwise operations in newer numpy versions. I am not terribly familiar with bitwise operations, but chat suggested the following change which fixed the issue for numpy 2.3.3

if maxPossible == 1:
	resetMask = ~(LISTED) & 0xFF
else:
	resetMask = ~(LISTED|EQUAL) & 0xFF

I am assuming this is more of a bandaid fix and that the type of some of the variables involved may need to change.
