joseLuís 6049e07d27 rust: continue refactoring the error system.
- made const NotcursesOptions constructors.
- refactor Notcurses constructors to return NcResult.
- pass NotcursesOptions by value, since it's Copy.
- update tests.
- add helper modules for Notcurses & NcPlane.
  - new initialization functions to be used in tests.
- BONUS:
  - refactor NcDirect
  - update examples.
