JSON format does not download any file, but saves all the metadata received about activities in a .json file.

Reduce maximum to 19, as everything bigger gets a 500 status:

Use `limit_maximum` instead of magic number

The old endpoint ('activity-search-service-1.2') doesn't seem to
work anymore for more than 20 activities, but is still useful for
the result summary (total numbers of activities)

The new endpoint ('activitylist-service') has an almost
completely different JSON output, which hasn't been adapted yet.

Also explain limit_maximum

No GPS data is indicated by HTTP status 204 (no content)

(reapplying commit 404165f to current state)

Write empty GPX file when there's no GPS data

This an adaptation of commit 7b0fcc7 to the refactored code

Cherry-Pick of commits 234c229 and a61dee1

 - restored order for a dozen or so columns
 - timestamp format is almost RFC1123 as used by Garmin

Add activity detail example file corresponding to the other examples

6 decimal places corresponds to a precision of 4 to 11 cm, way enough

Cleanup also other stuff like unneeded quote escaping for columns
that will never see a quote, etc.

no point in using a float with one decimal place

This format is almost the same that Garmin used
in the activity-search-service

Cleanup also other stuff like unneeded quote escaping for columns
that will never see a quote, etc.

no point in using a float with one decimal place for heart rate

The ticket is now extracted from the login response.
The cookies are not needed anymore, as well as the
voodoo calls to modern and legacy session.

For the post_auth call I chose just an URL that worked when
analyzing the HTTP traffic in the browser, maybe there are better
ones (with less payload)?
