Add Mayim to ORM section

[ahopkins]

What is this Python project?

It is an async ORM-like tool that acts as a DB interface layer to execute and hydrate SQL queries into Python objects.

What's the difference between this Python project and similar ones?

• Think of it as a one-way ORM: you provide the query, it provides the interface for managing the pool, executing queries, transaction, and model hydration
• Makes .sql files first-class citizens
• Emphasize data retrieval as a query action
• Provides customizable tooling for projects with complex schema requirements to get data from the DB into Python
• Easily enable developers to make full use of DB potential and not just limited toolset
