TypeORM Support for RateLimitPostgres
Hello @animir,

I noticed that in the docs for `rate-limiter-flexible`, you allowed for support with Sequelize & Knux for connections to Postgres (I haven't checked to see if the other DB drivers support this integration as well) - I was wondering if there would be support for TypeORM in the future due to its prominence amongst JavaScript/TypeScript-based ORMs? 

Thanks!
