Move JUMP pilot data documentation to cytomining/profiling-template

A lot of valuable documentation and notes have been taken in https://github.com/jump-cellpainting/pilot-data (private repo).

We should port over the common documentation from the JUMP repo to this upstream branch. It is likely that some of the documentation added in the JUMP repo is too specific and/or proprietary. Only the common documentation should be ported.

Also note that much of the instructions in pilot-data will be deprecated once the single cell aggregation options are improved via cytomining/pycytominer#111 and cytomining/pycytominer#112
