Printing timeseries

This PR tries to print layers with timeseries (see #1723)

The conditions for a layer to be printed in such way is `config.timeEnabled && timeSelectorEnabled == undefined && currentTime == undefined && multiPagesPrint`, with `multiPagesPrint`is true if no timestamp == "99991231" is present. Basically only `ch.swisstopo.zeitreiehen` correspond to these criteria. In background the print server has to generate the 169 PDF for each year individually and the reassemble them into on single PDF.

If the timeSelector is active and a year is selected, the year is printed on the PDF

IMPORTANT: Has to be merge with https://github.com/geoadmin/mf-chsdi3/pull/1086

Indeed there is a problem the time parameter is still there when we disabled the time selector.
