Changes iOS rate mapping from
to a more predictable mapping
(x-axis = plugin speech rate, y-axis = native speech rate, assuming AVSpeechUtteranceDefaultSpeechRate is 0.5)
Note: Speech rate heavily depends on the selected tts-engine and voice. There will not be a perfect cross-platform speech rate match. From experimenting with android and iOS tts-engines and voices this adjustment seems to be a good compromise.
We should also consider removing the rate adjustment completely though. See a similar discussion on react-native-ttshere. But that is another discussion.
