Compiler error in Bench — unresolved identifier MapboxVoiceController

[1ec5]

#2348 introduced a build error in the BenchTests target:

/path/to/mapbox-navigation-ios/BenchTests/BenchTests.swift:68:31: Use of unresolved identifier 'MapboxVoiceController'

mapbox-navigation-ios/BenchTests/BenchTests.swift

Line 57 in f2f78ce

let voiceController = MapboxVoiceController(navigationService: service, speechClient: speechAPI, audioPlayerType: AudioPlayerDummy.self)

This override is intended to capture and record any requests for audio from the Voice API. I think fixing the issue would require either mocking an entire MultiplexedSpeechSynthesizer, which might not give an accurate picture of the number of requests, or exposing a public setter for MapboxSpeechSynthesizer.speech. #2494 introduces a public getter for this property but keeps the setter private.

This is a bit challenging to fix, because #2348 eliminated the ability to inject a type other than AVAudioPlayer to initialize.
