Description
Expand a BED12 into a BED6 of in-frame mRNA positions, projected back to genomic coordinates. Default behaviour emits one row per codon (the 5' nucleotide); --step / --width / --frame control the stride, span and offset on the spliced mRNA. Useful for codon-level work on spliced features (e.g. ribo-seq P-site counts per codon, frame / periodicity QC, novel-ORF tiling).

positions along the spliced feature, with configurable frame,
step and span width via ext.args.
