Minor release addding a podfile

This is a minor release with a podfile added by a @slycoder

Resolve compatibility issues with react-native v0.47.0

Merge changes from @slycoder to address build issues with recent react native release, plus some cleanup.

Audio ducking and pitch

This release adds two new calls: setDucking(true) to enable lowering other applications output level while speaking (also referred to as "ducking"), and Tts.setDefaultPitch() to set pitch.

Thanks to @se1exin and @kamwong3 for their contributions!

Better error handling for setDefaultLanguage() calls and minSdkVersion aligned with 0.41.2 react-native

This release contains change from @IjzerenHein to provide better error reporting when calling setDefaultLanguage() with invalid language. Also, the minSdkVersion on Android has been set to 16 to align with react-native v0.41.2.

Optionally, turn off speech rate value translation

By default setDefaultRate(rate) API call performs translation of rate value to provide unified cross-platform behaviour. This release adds optional skipTransform parameter to this API call to turn translation off.

Resolve compatibility issues with react-native v0.40.0

This release of react-native-tts contains no new features or api changes, but addresses compatibility issue with React Native v0.40.0 on iOS.

Since this change breaks react-native-tts when used with older React Native releases, I'm bumping major version number.

Allow changing default speech rate

This version adds new API call setDefaultRate() to set default speech rate. Thanks to @maslianok for PR.

Change event format on iOS

This release changes format of TTS events on iOS. Now, event listeners will receive event parameter which is an object with utteranceId key, same as on Android.
