Text2Measurements API and Developer Portal

[mikepsinn]

I made a library for this:
https://github.com/FDA-AI/FDAi/tree/develop/libs/text-2-measurements

It works well for the test cases here:
https://github.com/FDA-AI/FDAi/blob/develop/libs/text-2-measurements/src/lib/statement-2-measurements.json

We'll have to add more test cases and set up automated testing with GitHub actions to avoid regression.

We can create a NextJS app in the apps folder with an API and developer portal for people to sign up, create API keys, and manage usage, similar to the OpenAI API key management system.
https://platform.openai.com/api-keys

Ideally, it would be easily deployable on Vercel.

We'll also want to implement caching for when we receive identical requests so we don't waste so much money on the LLM calls.
