fitCoordinates(...) resets heading/bearing to 0; moveCamera(...) also does not preserve heading/bearing

[KirillKaverin]

Before submitting a new issue

• I tested using the latest version of the library, as the bug might be already fixed.
• I tested using a supported version of react native.
• I checked for possible duplicate issues, with possible answers.

Bug summary

• Android (Google Maps): fitCoordinates(...) sets bearing to 0°; moveCamera(...) also does not preserve/restore non-zero bearing.
• iOS (Apple Maps): fitCoordinates(...) sets heading to 0°; moveCamera(...) also does not preserve/restore non-zero heading.
• iOS (Google Maps): fitCoordinates(...) sets bearing to 0°; moveCamera(...) also results in bearing 0°.

Steps to reproduce

1. Open the example app Home screen.
2. Ensure there are several markers (tap Add marker a few times in ControlSheet).
3. Rotate the map with a two-finger gesture to a visible non-zero heading/bearing.
4. Tap Fit markers (onFitMarkers → fitCoordinates(...)).
5. Observe heading/bearing resets to 0°.
6. Rotate again to non-zero heading/bearing.
7. Tap Move camera (onMoveCamera → moveCamera(...)).
8. Observe heading/bearing is not preserved (returns to 0°).
