Add encoding param to TTS Providers

[jcbjoe]

Problem Statement

All the TTS processors do not have a way to change the encoding. This seems to be due to Pipecat converting everything to PCM. However Im my case Im using ULAW for both STT and TTS to save on overhead of converting and resampling. Most STT processors in Pipecat have an encoding header so it only makes sense to add this to TTS processors. Right now I have copied of each processor and have to manually cherry pick updates when Pipecat updates.

Proposed Solution

Add an encoding parameter to the TTS processors

Alternative Solutions

Making copies of each processor and implementing it myself.
