Alternative `draw_lines` methods

[mtennekes]

I'm looking for alternative methods to draw lines between nodes. For instance, curved arcs

or half lines:

I'm happy to write my own functions, but would like to know what the easiest method is to 'submit' the created sf linestrings to the sfnetwork object.

So far I found out: that for an sfnetwork object x created with edges_as_lines = FALSE, I can add straight lines with

x = sfnetworks:::explicative_edges(x)

which runs sfnetworks:::draw_lines under the hood.

What would be helpful is a function like for instance::

x = explicitize_edges(x, fun = draw_curved_arcs, curvature = 15)

where

draw_curved_arcs = function(sfc_from, sfc_to, curvature = 30) {... }

is a just an example similar to draw_lines but user defined.

I like the idea to increase flexibility in this way. Will add it to the to-do list of v1.0
