Class to facilitate embedding generated documents to ChromaDb

[k-nearest-neighbor]

Simple traversal of the generated directory and adding to a local ChromaDB store.

from src.embeddings import Embeddings
e = Embeddings(debug=True)
e.persist_generated_file_contents()

Output:

embedding: generated/popup.js
embedding: generated/styles.css
embedding: generated/background.js
embedding: generated/popup.html
embedding: generated/shared_dependencies.md
embedding: generated/content_script.js
embedding: generated/manifest.json

persisted embeddings for 7 files.

This diff makes a few design choices though, like the introduction of a source directory.
