Ideas for annotation utilities

Currently using this dummy python script to gather annotation data but there is some method that I can see for converting this from a "dummy script" to a more standardized function

I want to address the idea of "caching the raw dataset" but also "an initial pull of data" into "some data is annotated" and finally towards "need more data to train my model, keep pulling more, but skip existing data"

```python
#!/usr/bin/env python
# -*- coding: utf-8 -*-

import logging
from pathlib import Path

import torch
from cdp_data import CDPInstances, datasets

from speakerbox.preprocessing import diarize_and_split_audio

dataset_dir = Path(f"cdp-datasets/{CDPInstances.Seattle}")
for audio_file in dataset_dir.glob("event-*/session-*/audio.wav"):
storage = audio_file.parent.parent.name
if not (Path(storage).exists() or Path(f"ANNOTATED-{storage}").exists()):
print("working on file:", audio_file)
print("storing:", storage)
torch.cuda.empty_cache()
diarize_and_split_audio(audio_file, storage_dir=storage)
