Steps to reproduce or a small repository showing the problem:

Expo has a SQLite API, but it is extremely rudimentary. I wanted to get some opinions on whether it's even possible to create a TypeORM driver for it.

• The openDatabase method accepts a name parameter and Expo's internal API will figure out the database location depending on the platform. This returns a Database object.
• The Database object has a single transaction method with 3 arguments: a callback function that accepts a Transaction object as its only argument, and error function, and a success function.
• The Transaction object has a single method with the following signature: executeSql(sqlStatement, arguments, success_callback, error_callback)

Comparing what's available in Expo's SQLite API to how TypeORM's Driver works, there doesn't seem to be a good way to do connection management, i.e. I can't 'open' or 'close' a connection to the database. Would it still be possible to create a driver for this or is it a lost cause?
