Fastapi

[riven314]

Changes

• set up fastAPI for model inference
• dockerized and refactor streamlit (app) and fastAPI (api) codebase
• set up docker compose to build 2 images together
• update README for setting up docker build
• resize image before sending POST request to API server if the image is too big

This entire file can and should be shared across model, app and api.

making 2 docker images to share a common parent utils folder is a bit hard to setup.
as an easier workaround, I simply created a common.py to contain common util function, and then duplicate common.py into app/src and api/src

Please adapt this to the configuration style we've adopted in model

This does not belong in api's config.
