Add to the Task/iTIP preview the GEO property
I propose adding to both the iTIP formatter and the Task preview the property GEO, and inserting after it a hyperlink to a map.
For the record, only precision of up to 5 digits after the decimal comma make sense. Libical parses GEO to floats and on request can convert the data to string, but the output is not the same as the input. Ie if the input is GEO:49.42612;7.75473
once the input is parsed, it is not possible to distinguish from the input GEO:49.426120;7.754730
by the libical API - https://github.com/libical/libical/issues/531 .
Opening in OpenStreetMap an URL with more than five digits after the decimal comma - https://www.openstreetmap.org/#map=19/49.426120/7.754730 - does first redirect the user to an URL where the extra digits are stripped - https://www.openstreetmap.org/#map=19/49.42612/7.75473 .
The fifth digit after the decimal comma corresponds to 1.1m precision.
