Is your feature request related to a problem? Please describe.

Pitch adjustment would be useful in some apps (e.g. changing pitch of voice or music).

Describe the solution you'd like

player.setPitch(1.0); // 1.0 being normal pitch

Describe alternatives you've considered

There is no other way to achieve this other than plugin support.

Additional context

This is easily implemented on Android, iOS might be more problematic (post below if you are able to share useful resources/documentation)
