Fails parsing BigQuery EXTRACT() format with time zone

[hrsma2i]

Thank you for this useful library!

This issue is similar to #21 .

When I parse the following SQL (a.sql) :

SELECT EXTRACT(DAYOFWEEK FROM CURRENT_TIMESTAMP() AT TIME ZONE 'Asia/Tokyo') AS as_timestamp

I caught the error:

> parse-sql@1.0.0 sql_parser_cst
> ts-node sql_parser_cst.ts

/Users/user.name/parse-sql/node_modules/sql-parser-cst/lib/main.js:40
            throw new FormattedSyntaxError_2.FormattedSyntaxError(e, sql, options.filename);
                  ^

↓ sql_parser_cst.ts

import fs from 'fs'
import path from 'path'
import { parse } from 'sql-parser-cst'

const sql_path = path.join('a.sql')
const sql = fs.readFileSync(sql_path, 'utf8')

const cst = parse(sql, {
    dialect: "bigquery",
    // These are optional:
    includeSpaces: true, // Adds spaces/tabs
    includeNewlines: true, // Adds newlines
    includeComments: true, // Adds comments
    includeRange: true, // Adds source code location data
})

console.log(cst)

Thanks for reporting. Will look into it when I get a chance. Been a bit busy lately.
