feat: describe what the app shows as a view

A view is a camera, data layers, visual style, map imagery and an aircraft,
military aircraft or satellite to follow, written in the share-link format
the app already restores. gods-eye-view/view builds, encodes and decodes one,
and share links take their style names from it. open_in_gods_eye_view now
builds its link from a full view: an area or camera, layers, style, map and
something to follow.
