Sqlalchemy-trino

Deprecated `sqlalchemy-trino` in favor of `trino-python-client`

`sqlalchemy-trino` was developed as _[Trino](https://trino.io/) (f.k.a PrestoSQL) dialect for SQLAlchemy._
Since trinodb/trino-python-client81, all code of `sqlalchemy-trino` is donated and merged into upstream project.
So now, this project is no longer active and consider as deprecated.

**NOTE**
[`trino-python-client`](https://github.com/trinodb/trino-python-client) 0.307 release with built-in SQLAlchemy driver (code donation from this repo).
To **avoid conflict between this package and the built-in dialect**, please update the `sqlalchemy-trino` to 0.4.1 or pinned `trino` to `0.360.0`

Start from 0.5, `sqlalchemy-trino` will going to maintenance mode, and all development should going to [`trino-python-client`](https://github.com/trinodb/trino-python-client)
