Screenshot Improvements #2

[ce-bo]

Feature request

Description

As a user, I want to see all parts of the view on my screenshot so that I have the same information on the screenshot as I do when having a open map.

Acceptance criteria

• [ ] Add a option to add/remove the legend to/from the screenshot output and use true as new default behavior
• [ ] Add a option to crop the view so that the map fills the complete screenshot with a tiny edge (edge size of up to 3% on each side). If the map is already zoomed in accordingly, do not change anything. The newly added legend and logo should be adjusted as well. This behavior should be turned off by default.

Development notes (optional Task Breakdown)

Please add one PR per acceptance criteria, building one feature on top of the other.
