Create an API endpoint which given a Standard JSON, suggests which CREs are the most likely mappings for this standard section

As an opencre or standard maintainer, I want to be able to import new standards or other security information very quickly in the CRE graph.
Given I have this information in a CRE Standard format, I need to find which CRE is best suited for linking with a specific section of my standard.
In order to do that I need an API call POST opencre.org/rest/v1/link/suggest where the body of the api call is a CRE Standard in json format.
OpenCRE then needs to reply with a json array of CREs that are best suited to match my standard.
e.g.
POST opencre.org/rest/v1/link/suggest

{"doctype":"Standard","hyperlink":"https://github.com/OWASP/ASVS/blob/v4.0.2/4.0/en/0x11-V2-Authentication.md","links":[],"name":"ASVS","section":"Verify that the challenge nonce is at least 64 bits in length, and statistically unique or unique over the lifetime of the cryptographic device.","sectionID":"V2.9.2"}]

Response:

[{"doctype":"CRE","id":"287-251","name":"Use a unique challenge nonce of sufficient size","tags":["Cryptography"]},{"doctype":"CRE","id":"287-252","name":"Some other CRE","tags":["Cryptography"]}]

Start by reading the CRE Standard definition in application/defs/cre_defs.py and reviewing the requested POST endpoint at opencre.org/rest/v1/link/suggest. Use the supplied ASVS example to understand the request and response shapes; done means the endpoint accepts a CRE Standard JSON document and returns an array of likely CRE mappings.
