[ios] bitrate is ignored in compressVideo

[FrikkieSnyman]

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

Calling compressVideo with bitrate has no effect, since the bitrate parameter is completely unused in the compressVideo function in VideoProcessor.swift:

react-native-media-toolkit/ios/VideoProcessor.swift

Line 752 in ab36723

bitrate: Double,

Library version
