feat(core): the packet capture's table after Java's Lauscher, measured against Java's own tables

Browse Source 
captureRows.ts builds Java's rows per frame (Lauscher.datenVorbereiten):
Ethernet; ARP, ICMP or IP; TCP or UDP; the data with Java's protocol
recognition; with addresses and ports or ports only. The comment stays
structured; captureCommentText says it with given words and numbers.

ScenarioNetwork writes Java's finished tables per card (Lauscher.getDaten,
German locale); all runtime runs are recorded again, NatRun has ttlOut.
expectSameCaptures compares both views for every frame. Fixed where the
engine differed: an ARP request's target MAC is the broadcast address,
an ICMP error's identifier and sequence number are 0 (RFC 792), and host
unreachable from a router carries the packet as forwarded. Not taken:
Java's lower-case broadcast address in a reply to 0.0.0.0, and the typo
'Exeeded'. RIP keeps its recordings: Java's staggered router start now
gives a different startup on this machine.
