This PR address the renaming of CytoPipe to CytoSnake.

cytopipe init -d *sqlite -m metadata -b barcodes.txt

After renaming:

cytosnake init -d *sqlite -m metadata -b barcodes.txt

cytosnake specific modules paths have also been changed:

before renaming

from cytopipe.cli.cli_docs import run_doc

After renaming

from cytosnake.cli.cli_docs import run_doc

The documentation has also been updated with the replacement with cytopipe to cytosnake.
