Gets a route from us (payer) to the given target node (payee).

If the payee provided features in their invoice, they should be provided via payee_features. Without this, MPP will only be used if the payee’s features are available in the network graph.

Private routing paths between a public node and the target may be included in last_hops. Currently, only the last hop in each path is considered.

If some channels aren’t announced, it may be useful to fill in a first_hops with the results from a local ChannelManager::list_usable_channels() call. If it is filled in, our view of our local channels (from net_graph_msg_handler) will be ignored, and only those in first_hops will be used.

Panics if first_hops contains channels without short_channel_ids (ChannelManager::list_usable_channels will never include such channels).

The fees on channels from us to next-hops are ignored (as they are assumed to all be equal), however the enabled/disabled bit on such channels as well as the htlc_minimum_msat/htlc_maximum_msat are checked as they may change based on the receiving node.
