Subject: Begin work on proxy server

Create a simple server with 3 endpoints:
* /create_session: Create a session and return its identifier.
* /set_transcript: Update a session's transcript.
* /get_transcript: Fetch a session's transcript.

Right now the session ID provides authentication *and* authorization.
There is no public/private ID so you have to trust whoever you share
your ID with.

IDs are long and generated by the server, so it should be somewhat
secure against low-effort hacking.

Other updates:
* Drop whisper_requirements.txt - no longer needed.
* Vendor curl to make it easier to interact with the server.

TODO:
* Fuzz test the server.
