feature request: Support map attribution printing

[sanak]

Currently, there seems to be no map attribution printing functionality as configuration, but it would be nice to support it from a point of view of license.

The following is OpenStreetMap attribution guidelines for printed maps.
https://osmfoundation.org/wiki/Licence/Attribution_Guidelines#Books,_magazines,_and_printed_maps

Books, magazines, and printed maps

For a printed map and similar media (that is ebooks, PDFs and so on), the credit must appear beside the map if that is where other such credits appear, or in a footnote/endnote if that is where other credits appear, or in the “acknowledgements” section of the publication (often at the start of a book or magazine) if that is where other credits appear. The URL to openstreetmap.org/copyright must be printed out.

You can put an attribution text in the JasperReport template, do you need something other?
What do you imagine?
Having an attribution sting on the layers, and the print will create a string array with all the attributions, and put it in the context?

@sbrunner Thanks for your reply!

Yes, it's possible to add attribution text directly (or via parameter) in the JasperReport template, but I thought this is a common use case, so supporting it in this library side is nice.

Yes, my image is similar with other frontend map libraries (OpenLayers, Leaflet, etc.),

• OpenLayers example: https://openlayers.org/en/latest/examples/attributions.html
• Leaflet example: https://leafletjs.com/examples/quick-start/

but more simple map level configuration (like attributes/map/attributions as text string) may be enough.

And control configuration image is similar with current scalebar and northArrow.
