Cityseer

Catches if both None for pairing distances and betas.

Cityseer's underlying internals have been reimplemented in rust, therefore removing the reliance on `Numba`.

This offers several improvements:
- Better performance
- Unlike `Numba` there is no need for the underlying code to compile on first run
- Fewer issues related to `Numba` release cycles, which tended to lag official Python releases and sometimes introduced unexpected behaviour.
- `Numba` forced some difficult design patterns due to not being able to use `Numba` classes for parallelised code, and otherwise a reliance on numpy arrays which had to be passed around from function to function. The rust version offers more elegant approaches to handling and sharing data structures.

The higher level API is similar, though in has been simplified in several situations. Please see the API docs for more information.

Fixes param typo in plotting function.

Maintenance release with package bumps.

Updates code to work with `shapely` v2.

- Updates rtree syntax to work with the `shapely` v2 API.
- Adds a workaround for `shapely` `ops.substring` which currently raises an error for LineStrings with Z coordinates.
- Updates packages and minimum version requirements accordingly.

Fixes an issue (65) where negative coordinates would raise an error.
