Selecting specific stains when reading merscope files into a sdata object.

[omiethescientist]

The merscope image files that I use are currently quite big, and it is often useful for me to only select specific stains. Currently it is hard coded in the merscope function to read in all stains. However, it is an option in the _rioxarray_load_merscope function. It would be nice to set this ourselves as one of the kwargs or as a keyword argument in the merscope function itself.

Hi @omiethescientist and thanks for the suggestion. Would you like to try making a PR for addressing this? We chose to keep spatialdata separate from spatialdata-io to encourage contributions from the community and I think this addition would be useful for the other users.

Sorry for the late response @LucaMarconato. Yes, I could definitely get a small PR done for this. I already have a small fix that allows you to include it as an additional kwarg in imread_kwargs. However, I know the code could be cleaner if I just passed it as an additional keyword argument in the funciton. What do you think?

Yes @omiethescientist, sounds good to me. Thanks!
