Handle qualified table names

[crishoj]

In my project, Prisma is generating SQL queries where table names are prefixed with a schema name, e.g.:

SELECT `main`.`Plc`.`id`, `main`.`Plc`.`name`, `main`.`Plc`.`enabled`, `main`.`Plc`.`createdAt`, `main`.`Plc`.`updatedAt

This means that the regex in getTableFromQuery wouldn't match, and the adapter would fallback to non-declared types. (Which then would break handling of DATETIME columns, since these appear as numbers at run-time...)

I propose the change below, to also match qualified table names, and then using the form PRAGMA ${tableInfo.schema}.table_info(${tableInfo.table}) to get declared types.
