How to deal with antisense transcripts

Lines 67 to 70 in aba9107

	strand = {orf.strand for orf in self.orfs}
	if len(strand) > 1:
	raise ValueError("Can't plot isoforms from different strands")
	self.strand: Strand = list(strand)[0]

Currently - the isoimage code only takes in same-strand ORFs for plotting.
We need to think about what to with antisense transcripts, which are prevalent in our long-read data, as well as GENCODE.
