perf: Load pegjs files conditionally

[TrevorBurnham]

The .pegjs files total ~1.45MB and are all loaded upfront. I would guess that most users (like myself) only use one SQL dialect in their project, so loading only that specific parser would significantly reduce their browser's download time (nm, I see that's what the separate <dialect>.umd.js files are for) or their Node.js process' startup time.

// or you can import specified database parser only, it's about 150K

<script src="https://unpkg.com/node-sql-parser/umd/mysql.umd.js"></script>
<script>
      window.onload = function () {
        // Example parser
        const parser = new NodeSQLParser.Parser()
        const ast = parser.astify("select id, name from students where age < 18")
        console.log(ast)
        const sql = parser.sqlify(ast)
        console.log(sql)
      }
    </script>

const { Parser } = require('node-sql-parser/build/mysql');
const parser = new Parser();
const ast = parser.astify('SELECT * FROM t');

Ahh, I missed that. The package.json doesn't declare any entrypoints other than index.js. Would you accept a pull request to add them?

Of course, Thanks for that.
