Initial work on move to implot 0.7 compatibility. See notes.

- This updates the bindings generator, the low-level bindings as
  well as the higher-level bindings and the examples to work
  with a newer master of cimplot that links to implot 0.7.
- Several things are not done properly yet:
  - Contexts can be created and as long as they are not dropped
    things work out (shown in the examples). However, this should
    be done more imgui-rs like, where operations that require a context
    make that explicit by requiring a context reference to be passed.
  - The README has not been updated yet to all the new features that
    were added.
