Fault topology Bug [BUG]

[markjessell]

Describe your issue

The output from map2model of fault-strat topology as

unit-fault-intersection.txt

is not completely carried over to

group-fault-relationships.csv

Minimal reproducing code example

unit-fault-intersection.txt:
0, jc, {1}
1, jm1, {0, 1, 3}
2, jm2, {0, 1, 3}
3, l2, {0}
4, l3, {2, 3}
5, l4, {1, 2}

group-fault-relationships.csv:
group	Fault_0	Fault_2	Fault_1	Fault_3
all	1	1	1	0

So Fault_3 is forgotten
