Enhanced user input (#260)

* use a new toolkit for user prompting: questionary (patched).
* multiline questions.
* conditional questions.
* new toolkit for ui tests: pexpect.
* fix lots of tests.
* fix windows builds with newer poetry-dynamic-versioning.
* linters and mypy are now tests, to have faster ci.
* update deprecated ci commands.
* removed dependencies from old times.
* Remove toml 0.5+ syntax (dotted keys)
* Use powershell where syntax is compatible
* Change skip to xfail
* xfail pexpect tests on windows. I'm tired of trying to make it work
* more docs
* possibly something more.
