Allow uint32 & uint64 for Start & End positions?

[jeanmonet]

Hi, is there any reason not to allow uint32 & uint64, otherwise can we enable compatibility?

File anaconda/envs/bio12/lib/python3.12/site-packages/ncls/__init__.py:20, in NCLS(starts, ends, ids)
     [18](anaconda/envs/bio12/lib/python3.12/site-packages/ncls/__init__.py:18)     return NCLS32(starts.astype(np.int32), ends.astype(np.int32), ids)
     [19](anaconda/envs/bio12/lib/python3.12/site-packages/ncls/__init__.py:19) else:
---> [20](anaconda/envs/bio12/lib/python3.12/site-packages/ncls/__init__.py:20)     raise Exception("Starts/Ends not int64 or int32: " + str(starts.dtype))

Exception: Starts/Ends not int64 or int32: uint32
