feature request: odgi props

[adadiehl]

odgi props: Describe a node's properties, including label length, sequence, depth, incoming and outgoing degree. Required args -i <input graph.og>, -g graph position ([[node_id][,offset[,(+|-)]**]**]) or node range (>405>410) or -G file with one graph position or node range per line. Options: -p/--paths-covered print all paths covering the given node, -r/--ref-path <path> Required if supplying node ranges. Reference path to traverse, printing props for each node in range.
