fix: consider user selected timezone while exporting the reports

[metapraveen]

problem:
Time in CSV exported reports are always in UTC timezone irrespective of user
selected timezone in the UI. There are use case when time in the exported
reports should be other timezone than UTC.

fix:
plywood passes the user selected timezone to format function here
https://github.com/implydata/plywood/blob/master/src/datatypes/dataset.ts#L343
We can use that to get time in the user selected timezone. The time in reports
will also have information about timezone because of ISO format.

I'm very picky when it comes to naming constants :)

We will discuss internally if we want this change, give us some time.

FYI:

> moment().format("YYYY-MM-DDTHH:mm:ss.sssZ")
"2021-02-16T17:10:28.2828+01:00"

Used this format because before it used to return .toISOString(). So whenever user looks at exported reports he can know on which timezone this report is for.

Sorry, I put this comment here for fellow reviewers, so they can see what output your change would produce :)

But have you tried importing this format into excel? Does excel/google sheets correctly parse this format?
