cooler version 0.8.11 incompatible with numpy 1.24

[lldelisle]

Hi,
I got an error:

>>> import cooler
/home/ldelisle/.conda/envs/test2/lib/python3.8/site-packages/cooler/util.py:690: FutureWarning: In the future `np.object` will be defined as the corresponding NumPy scalar.  (This may have returned Python scalars in past versions.
  columns, dtype=None, index_columns=None, index_names=None, default_dtype=np.object
Traceback (most recent call last):

    raise AttributeError("module {!r} has no attribute "
AttributeError: module 'numpy' has no attribute 'object'
>>> 

This error seems to be linked to numpy 1.24 as import cooler works if I use numpy 1.23.
Should I update the conda recipe?

I wrote a PR to update the bioconda recipe: bioconda/bioconda-recipes#38816

@nvictus , couldn't the solution be to use np.object_ instead?..

Yes, @robomics has already made the PR and I merged it earlier this week.

v3.9 will be coming out shortly and this will be fixed. In the meantime, updating the conda recipe for 0.8.11 or 0.8.* makes sense.

Should I update the conda recipe?

Yes. Thank you, @lldelisle!
