Android stop fix

New

• new parameter localeId on the SpeechToTextProvider listen method supports selecting a
  non default languge for the recognizer when using the provider.

Fix

• A work around for a bug in Android 10(29) that made stop and cancel not work. The plugin now
  calls destroy on the Android SpeechRecognizer which terminates the listen session immediately.
  There is a downside to this approach in that it does not always report results that were in process
  when destroy was called, however it does mean that stop works.
• The example for SpeechToTextProvider, provider_example.dart had an error that made it always
  use the default language and ignore the drop-down selection. This has been corrected.

Doc update

Fix

• Updated the version number in the readme file, which I forget to do, every single time.

iOS final Results fix

New

• new parameter sampleRate on the listen method supports some older iOS devices by allowing
  customization to support the expected hardware sample rate. 44100 works with some older devices.

Fix

• pauseFor now times out closer to the expected time and more reliably. Duplicate partial results were
  causing it to extend previously.
• finalResult is now reliably true on the last result on iOS when pauseFor or listenFor timeout or
  stop is called directly. Previously it would only return true when the stop happened almost immediately

Provider

New

• new parameter onDevice on the listen method enforces on device recognition for sensitive content
• onSoundLevelChange now supported on iOS
• added compile troubleshooting help to README.md
• SpeechToTextProvider is an alternate and simpler way to interact with the SpeechToText plugin.
• new provider_example.dart example for usage of SpeechToTextProvider.

Fix

• on iOS handles some conflicts with other applications better to keep speech working after calls for example

iOS sound handling improvements

New

• improved error handling and logging in the iOS implementation
• added general guides for iOS to the README
• moved stress testing out of the main example
• iOS now defaults to using the speaker rather than the receiver for start /stop sounds when no headphones

Fix

• iOS now properly deactivates the audio session when no longer listening
• start and stop sounds on iOS should be more reliable when available

Error handling on Android

Breaking

• listenFor now calls stop rather than cancel as this seems like more useful behaviour

Fix

• Android no longer stops or cancels the speech recognizer if it has already been shutdown by a
  timeout or other platform behaviour.
• Android no longer tries to restart the listener when it is already active
• Now properly notifies errors that happen after listening stops due to platform callback rather than
  client request. See #51

Separate timeout errors

• error_timeout has been separated into error_network_timeout and error_speech_timeout

Partial results & cancel on error

• hasPermission to check for the current permission without bringing up the system dialog
• listen has a new optional cancelOnError parameter to support automatically canceling
  a listening session on a permanent error.
• listen has a new optional partialResults parameter that controls whether the callback
  receives partial or only final results.

Multiple transcriptions

New

• speech recognizer now exposes multiple possible transcriptions for each recognized speech
• alternates list on SpeechRecognitionResult exposes alternate transcriptions of voice
• confidence on SpeechRecognitionResult gives an estimate of confidence in the transcription
• isConfident on SpeechRecognitionResult supports testing confidence
• hasConfidenceRating on SpeechRecognitionResult indicates if confidence was provided from the device
• new SpeechRecognitionWords class gives details on per transcription words and confidence

Fix

• speechRecognizer availabilityDidChange was crashing if invoked due to an invalid parameter type
• Added iOS platform 10 to example Podfile to resolve compilation warnings
