Change type-annots to use `httpx.Response`

Code base is already ported for `Qt6` so this removes the pyqt5 dep,
adds latest pyqt6 as well as buncha other updates:

- add `xonsh` and ptk as dev deps for those of us using wacky shells ;P
- bump compiled deps as needed for python 3.12 (`numpy`, `numba`)
- add `httpx` and drop `asks` since the latter is zombied and not compat
  with other libs on 3.12.
- add `ruff` linting ignore rules for the new `.ui.qt` shim mod layer.
- few other deps updates to latest versions.
- add in the `keywords` and `classifiers` sections from the old
  `setup.py`.
