Adjusttext

Now attempting to prevent arrow crossings. Please report if you encounter any issues with this feature!

Some other small fixes.

Release for compatibility with numpy 2.0.

Also now adjust_text returns the modified text objects and created arrows.

objects=` argument is fixed, and eve works with a PathCollection

Fixed bugs in some calculations, so better results (more similar to the original implementation with the old engine!)

Much faster in many cases - error can actually reach 0 and iterations stop before reaching time/iteration limit.

Small improvements to docs and examples.

Minor changes, removed unnecessary pandas import.

Bump version
