The name router is ambiguous given its usage in other contexts

[Reecepbcups]

From Justin in the previous repo: strangelove-ventures/packet-forward-middleware#10

router is used in a few different contexts across modules/in the SDK so perhaps renaming to ibcrouter would be less confusing

"I think pfm or forward are valid choices! typically when I import the middleware into other repos I end up creating an alias called forward"

"I think a lot of apps already rename the import to packetforward so this might be a good candidate as well"
