feature request: odgi ranges

[adadiehl]

Based on odgi position. Given a graph position (e.g., -g [[node_id][,offset[,(+|-)]**]**]), range of graph node IDs (e.g., -g >6050>6060), or BED file with ranges relative to any path in the graph, return chromosome, start, and end position(s) in standard BED format in the frame of the path given with -r. Include additional option -n to exclude start and end nodes of a node range, to be used, e.g., to obtain BED coordinates of bubbles, excluding bordering invariant nodes constituting the VCF ID field in vg deconstruct output.

# Single node example: return chrom, start, and end of sequence associated with the given node:
odgi ranges -i graph.og -g 6040,0,+ -r HG005#1#chr1
# chrom start end
HG005#1#chr1 11651  11850

# Range of nodes, without -n: return chrom, start, and end of sequence spanning all nodes in the range, traversing all nodes in the given reference path:
odgi ranges -i graph.og -g >6040>6050 -r HG005#1#chr1
# chrom start end
HG005#1#chr1 11651 14711

# Range of nodes, with -n: same as range without -n, but exclude start and end nodes, returning only the range of nodes in between:
odgi ranges -i graph.og -g >6040>6050 -r HG005#1#chr1 -n
# chrom start end
HG005#1#chr1 11851 14350

# Ranges given in BED file: lift over BED coordinates from the input path to the path given with -r:
odgi ranges -i graph.og -b <input-ranges.bed> -r HG005#1#chr1
#chrom start end
HG005#1#chr1 11851 14350
