MicStream.microphone() silences audio player plugins

[asmodeoux]

I'm trying to use this mic stream in an app and play some sound effects at the same time. But once the mic stream initializes and starts listening, all the sound effects are silenced. I tried just_audio and audioplayers libs and both fail to play any sound when this mic plugin is active. This behavior is only in iOS, in Android both audio input and output work well at the same time. What might be wrong and how can I fix it?

I found what's causing this, the plugin sets the AudioCategory in iOS to record-only, while I think it should be playAndRecord, or maybe even configurable:
try audioSession.setCategory(AVAudioSession.Category.playAndRecord, mode: .measurement, options: [.defaultToSpeaker, .mixWithOthers])

hey, thank you for taking your time to look into this yourself already.

It's very likely that changing the category will resolve this issue. I cannot reliably test this, though, and therefore cannot fix this myself.
I'd appreciate if you can fix this, make sure it runs, and open a PR.
I'm happy to help with anything in the process, as long as it isn't platform-specific.
