User description

Implements API for order quoting and creation.

Test Plan

yarn && yarn dev

curl -X 'POST' \
  'http://localhost:3000/api/quote' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "network": "mainnet"
  "sellToken": "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48",
