[Feature]: Extend transcription provider support for Benchmarking

[applebaconsoda123]

Brief Description

Enhance Vocode's benchmarking capabilities by integrating additional transcription services such as Azure Speech to Text, Rev.ai, and others. This expansion will allow users to comprehensively evaluate and compare the latency and accuracy of various speech-to-text transcription services directly.

Rationale

Benchmarking different transcription services is important to those aiming to minimize latency in their voice-based applications- currently Vocode's benchmarking tool is limited to Deepgram and AssemblyAI. Users would gain the ability to make more informed decisions based on a broader dataset.
