Unable to use table with schema name
Hi there,

We are using your library with the postgres driver and a table defined in a different schema (not public). As introduced by this [commit](https://github.com/animir/node-rate-limiter-flexible/commit/b98a9a504036771ab5a3005627da4aba57d437ae) you are using quotations for the table name parameter which makes it impossible to work for a table prefixed with the schema name.

See our implementation below:

` new RateLimiterPostgres(
					{
						// Database config
						storeType: 'knex',
						tableCreated: true,
						tableName: 'server.rate_limiters',
						// Limiter config
						keyPrefix: name,
						points,
						duration,
					},`
