Add native support for OracleDB

[PhilippSalvisberg]

Background

After you've implemented #37 I opened an enhancement request for the node-oracledb driver (see oracle/node-oracledb#1629). This was accepted and implemented in version 6.4.0 of the node-oracledb driver. Oracle also opened a PR for the type definition (see DefinitelyTyped/DefinitelyTyped#69327). This PR has been accepted and is now included in version 6.4.0 of @types/oracldb on npm.

So, OracleDB is now a first-class citizen as PostgreSQL and MySQL (when using sql-template-tag >=5.2.0, node-oracledb >=6.4.0 and @types/oracledb >=6.4.0).

Change

This PR updates the README regarding query.statement and query.values which are now automatically considered by the latest node-oracledb driver.

That is awesome, thank you! Did you also want to update the package.json to align (description and keywords):

sql-template-tag/package.json

Lines 4 to 15 in 7368e53

	"description": "ES2015 tagged template string for preparing SQL statements, works with `pg` and `mysql`",
	"keywords": [
	"sql",
	"template",
	"string",
	"tag",
	"es2015",
	"es6",
	"pg",
	"postgres",
	"mysql"
	],

Happy to merge either way, this is really cool to see.

Separately, I did see this comment:

1. bulk insert or executeMany doesn't work as the expected positional binds, values differ in syntax from what the sql function returns..
2. RETURNING Clause with out binds for INTO clause don't work as the sql function expects the binds to have input values given.

Do you happen to know what those refer to and whether I should look into fixing anything in this library?

(...) update the package.json to align (description and keywords)

Done. Also added sqlite.

Do you happen to know what those refer to and whether I should look into fixing anything in this library?

The comment refers to cases where simple positional parameters (:1, :2, etc.) cannot be used as binds. See examples in 7.3. DML RETURNING Bind Parameters and 8. Executing Batch Statements and Bulk Loading. In such cases the library cannot be used. IMO that's good enough.

Perfect, makes sense. I can create a follow up discussion if you're interested in solving them but it doesn't seem urgent. At least the batch statement use-case seems simple to do across all dialects, I can tag you on an attempt to solve it when I have a chance.
