Adds several new features, outlined here: https://docs.google.com/presentation/d/1UDikmED-dG3zwXz2uyavRNr5sGzjas7wPbP4IjDQ3HY/edit#slide=id.p1

* fixed several bugs with multi-channel recordings including saving tiffs, aligning by 2nd channel, saving meanImg_chan2 and saving F_chan2 and Fneu_chan2 in the merge GUI.
* added cellpose support to suite2p, run `pip install cellpose` in your suite2p environment and check out the `ops['anatomical_only']` key.
* added support for optional default cell diameter
* fixed bruker tiff bug
* added `ops['norm_frames']` (set to True by default) to decrease noise in registration
* added automated row removal for scanbox files

- removes a key which made `ops.npy` prohibitively large
- fixes a bug with loading NWB files
- fixes a bug with meanImg saving with align_to_chan = 2
- fixes a bug with plane folder loading after folders have been moved

* reorganization of tests
* addition of mesoscope tiff test
* removal of ops1 from pipeline and GUI
* new key `ops['classfile']` that allows user to specify classifier used in pipeline
* removal of scikit-image dependency
