[FEATURE] Allow for long press ping

Is your feature request related to a problem? Please describe.
I am using a Mac & trackpad and I like the ability to quickly Ping with one hand. I currently have the Ping set to RightClick, however it is frustrating that whenever I use the RightClick+hold to move the map, it also creates a Ping.

Describe the solution you'd like
It would be great if there was an option to only create a Ping if a button/click is long pressed or something along those lines. That way any short RightClick or RightClick+hold don't create Pings while stilling allowing Pings to be done by a simple one-handed click.

Describe alternatives you've considered
I originally had the Ping on LeftClick but that made it even worse since a lot of other things use LeftClick. I've tried setting the Ping to shift+RightClick which works fine but it is not as handy since it is no longer a quick one handed gesture - a lot of my Pings are done after mouse movement so having it associated with a simple one-hand click right after I use the trackpad/mouse makes the flow work really well. It is possible that maybe long press is already working but it seems like on a Mac trackpad it just thinks it is a normal short click.

Additional context
Nothing else to add - no worries if you can't add this feature. I already really like the mod and appreciate it - my group uses a lot of pings! :)

The issue names no files, tests, or entry points. Start by locating the Ping input binding and map-movement handling, then determine how a long press should differ from a short click or held right-click; done means the configured gesture creates a Ping without interfering with map movement.
