Does not support cron range (',','-')

The package doesn’t seem to support cron statement w/ range syntax, such as "00 00 * * * 6-7" or "00 00 * * * 6,7", is this a bug or feature request?

Behavior noticed using the following…

Version: 2.4.1

Environment:

Local time: Sun 2017-07-02 13:59:22 PDT
Universal time: Sun 2017-07-02 20:59:22 UTC
RTC time: Sun 2017-07-02 20:59:22
Time zone: America/Los_Angeles (PDT, -0700)

Repro:

// expected
00 00 * * * 6-7 2017-07-02T14:00:00-07:00
00 00 * * * 7 2017-07-02T14:00:00-07:00
00 00 * * * 6,7 2017-07-02T14:00:00-07:00

// actual
00 00 * * * 6-7 2017-07-08T00:00:00-07:00
00 00 * * * 7 2017-07-02T14:00:00-07:00
00 00 * * * 6,7 2017-07-08T00:00:00-07:00

Script (using moment-timezone for clarity):

const cronParser = require("cron-parser");
const moment = require("moment-timezone");

let timezone = "America/Los_Angeles"
let patterns = [
  "00 00 * * * 6-7",
  "00 00 * * * 7",
  "00 00 * * * 6,7",
];
let args = { 
  iterator: true,
  currentDate: '2017-07-02T13:25:00-07:00',
  tz: timezone,
};

patterns.forEach((pattern) => {
  let iterator = cronParser.parseExpression(pattern, args);
  let next = moment(iterator.next().value.toISOString()).tz(timezone).format();
  console.log(pattern, next);
});

@BuZzy1337 haven’t really had time to look into this. It’s still top priority tho. Trying to look into this as soon as possible. Thank you reminding this!

Any solution in sight for this issue?
