Crash on some Android 14 physical devices when stopping recording.

[siddharthadevops]

(record: ^5.1.2)

Android device.

App crashes due to an unhandled excepcion

Add your record configuration
RecordConfig get _recordConfig => const RecordConfig(
bitRate: 64000,
sampleRate: 16000,
numChannels: 2,
);

Record and stop the recording.

Add any other context about the problem here.

I debugged the bug and found out that for some reason the OnError function is called after stopping playback and discarding the Recorder object on the Flutter side.

E/AndroidRuntime(32182): on com.llfbandit.record.record.encoder.MediaCodecEncoder.onError(MediaCodecEncoder.kt:161)

As a workaround, I added a variable (ThreadSafe) to ensure that stopAndRelease is not called twice. And I also converted the mFinished variable to support multithreading. This solved the problem.
I didn't propose a PR because I have zero experience developing in Kotlin and I'm not sure how multitasking works with this package and in Kotlin in general.
