Add option for “distance by _long_ tap”

[leokennis]

Describe the idea (required)

Hi, I'm a new OsmAnd user. I like the "distance by tap" feature (https://osmand.net/docs/user/widgets/radius-ruler#distance-by-tap-tool) but once enabled, it really calculates the distance on every tap. This includes when adding points while creating a route, when clicking a POI for more info etc.

To me it would make sense to include an option to keep the normal tap as it is, and have it show the distance to a point only on a long tap / double tap / something else than a regular tap.

Tell us about the expected behaviour (required)

Old situation: with “distance by tap” enabled, every tap on screen shows the distance marker.

New situation: with “distance by tap” enabled and set to a long tap, a normal tap on screen does not show the distance marker. Only a long tap does.

Tell us about alternatives you've considered (required)

Right now the only option to avoid the behavior is to disable “distance by tap”.

Context (optional)

If I remember well, in the oldest versions of OsmAnd (talking about 1.9/2.x), it was possible to have a widget to enable or disable a "measuerement tool": it was actually very useful since I could enable it only when needed, then disable it and have OsmAnd working "as usual".

Maybe it might be re-introduced; not sure if now we can already assign that function to a custom button.

@leokennis , I think there is a workaround: (quite uncomfortable, indeed): you can create a dedicated profile with Distance by tap option pre-enabled, and switch to it when some measurement is needed, then switch back to the previous one. Not the best option, IMO... but it might work.

I second the need to refine this feature some.

Distance by tap is very useful, but it breaks fullscreen mode. Maybe:
long-press= distance
short press = fullscreen

Long press calls context menu
