16755	[Patch] Cut overlapping GPX layers when merging	Bjoeni	team	"followup of #16681
> Ideas that could implemented in the future

> allow multiple tracks to be processed and prioritized (from different sources, e.g. GPS + phone + Google Timeline) [cut overlapping parts of less important tracks and replace by more important ones -> merge before handling]

This patch allows the user to cut timewise overlapping tracks and to connect them on the cuts when merging layers.

I had to modify the `AbstractMergeAction`: I kept it abstract and all public signatures the same, but please have a closer look at that before patching.
