resampled to the desired output sample rate.
- Fixed an issue with the `TwilioFrameSerializer` and `TelnyxFrameSerializer`
where `frame.audio_out_sample_rate` was incorrectly used in place of
`frame.audio_in_sample_rate`, which caused audio input detection to fail when
using different input and output sample rates.
where `twilio_sample_rate` and `telnyx_sample_rate` were incorrectly
initialized to `audio_in_sample_rate`. Those values currently default to 8000
and should be set manually from the serializer constructor if a different
value is needed.
