Drop IPython and use python-prompt-toolkit?

[goodboy]

Consider dropping IPython from the switchy cli since we can get auto completion for free with the std lib.

@tgoodlet And what do you win from dropping it? just removing a dep?

[goodboy]

Yeah and I was thinking about maybe moving to ptk eventually instead. If ^ gets us completion then what are we really needing IPython for?

[goodboy]

Alright I just tried rlcompleter thing out and it's no good. Probably should have noticed in the docs that it says

by completing valid Python identifiers and keywords.

So it's really quite horrendous for working with the originator instance binding.
