rename Squish to Squeeze

[gemmaellen]

Renamed "Squish" to "Squeeze" in:

• both pipeline/operations/dask and pipeline/operations/numpy
• tutorial notebooks
• old documentation

One minor note: I hope I haven't messed anything up with the notebooks. I think I was only changing references to that one function, but let me know if the act of opening them in my own JupyterLab has altered something that I need to put back.

The coding looks great at a glance. I will proceed to running some of the notebooks and checking the automated test coverage shortly.

It's a shame these files don't have pre-existing test coverage. I tried executing the squeeze in a notebook, but it failed for reasons that appear unrelated to your change. The rename itself caused no issues. So I think the PR is okay, but I look forward to getting some test coverage around these files in due course.
