Incompatible version. And `click` v8 lib already has types.

* Explicitly creating subdirs for each command step seems wrong. Is there a
  better way?
* We think data
  futures (https://parsl.readthedocs.io/en/stable/userguide/futures.html#datafutures)
  might be the "right" thing to use for chaining commands instead of calling
  `result()` for each, but that requires us to know in advance what the output
  filename of each command id. Are there cases where a command could output
  multiple files?

Flesh out Nox usage docs

Unfortunately, this isn't quite what we were looking for. We actually
want to `apply`, not `create`, because with `create` (the imperative
method) we need to deal with cleanup of the previous object, or patch
it. With `apply` (the declarative method), we specify what we want and
kubernetes takes care of the rest.

NOTE: Some imports still need fixing

`curl` complains when the URL doesn't contain a filename that it can use when
given a directory with `-O`. `wget` can fetch the remote resource and figure out
the filename when given a dir to write to with `-P`

Latest parsl code + added `wget`

Raises an error when variables are unset.

This feels increasingly "wrong". By injecting values into templates representing
python code, we don't gain any of the advantages of our usual tooling around
types, code formatting, syntax checking, etc. We only find out about e.g.,
syntax errors and incorrectly formatted function calls (kwarg vs positional, as
in this case) until we try to execute the program.

This uses the remote server's name for a file when it isn't available in the url path

There is no pypy 3.11
