[fdsnws2inv] Too conservative restrictedStatus conversion

[andres-h]

There is an issue with partially restricted networks and stations (eg., rolling embargo). restrictedStatus="partial" is translated to restricted="true", in which case all child elements are considered restricted by fdsnws, regardless of the value of their restricted attribute.

Suggest changing:

sc_x->setRestricted(x->restrictedStatus() != FDSNXML::RST_OPEN);

to

sc_x->setRestricted(x->restrictedStatus() == FDSNXML::RST_CLOSED);

True restrictedStatus could be preserved via JSON comments. Should I do a pull request?
