core: stdcm: apply mareco to the final envelope

[eckter]

We try to apply the standard allowance as one mareco computation over the whole path. If it causes conflicts, we split the mareco ranges so that the passage time at the points of conflict stays the same as the one we expected when exploring the graph.

It comes with a few extra tools in EnvelopeDebug, to plot space-time charts.
