tiff -> mrmatrix?

[mccalluc]

It's on our plate to be able to handle tiff files. I do remember your wariness about adding support for more matrix forms beyond TSV but...

• For our audience, we want to be able to say that it can be handled out of the box.
• Big tiffs could get very, very, big if translated into an intermediate TSV
• Getting the details of the tiling right is finicky... Now that it's done, I feel like the TSV parser itself should really just parse to a numpy array, and then do the same thing for tiffs with this: https://pypi.org/project/tifffile/

If this is going to happen, would you rather the work be done in clodius, or should there be a new clodius-imaging where it would go?

Also, just a gut check: You do feel confident that we're not getting too far into wheel reinvention here? I think there's an alternate route, where we work on the client side to handle a wider range of image tiling formats.

Would a DAG diagram of filetypes -> tiletypes -> tracktypes be useful?
