In arendsee/synder: Use Synteny to Filter Genomic Search

print all blocks with contiguous set ids

1	c_dump(syn, swap, trans, k, r, offsets)

`syn`	synteny map file name
`swap`	reverse direction of synteny map (e.g. swap query and target)
`trans`	score transform methods, single character
`k`	match fuziness, integer
`r`	score decay rate, 0 means no context, high means more context
`offsets`	4-element integer vector of [01] offsets (start/stop offsets for the synteny maps and the GFF)
