Add new data reader: AssemblyAIAudioTranscriptReader

[patrickloeber]

This PR adds a new data reader AssemblyAIAudioTranscriptReader that allows to transcribe audio files with the AssemblyAI API and loads the transcribed text into documents.

• add new reader with class AssemblyAIAudioTranscriptReader
• add README
• add unit tests. The test use a MockerFixture and don't use API calls
• Add new dev dependency pytest-mock

Description

At its simplest, you can use the loader to get a transcript back from an audio file like this:

from llama_hub.assemblyai.base import AssemblyAIAudioTranscriptReader

audio_file = "https://storage.googleapis.com/aai-docs-samples/nbc.mp3"
# or a local file path: audio_file = "./nbc.mp3"

reader = AssemblyAIAudioTranscriptReader(file_path=audio_file)

docs = reader.load_data()

To use it, it needs the assemblyai python package installed, and the environment variable ASSEMBLYAI_API_KEY set with your API key. Alternatively, the API key can also be passed as an argument.
