Make intron coords consistently [1-based) the same way start/end are

f0 <- tibble(
  seq_id="a",
  start=1,
  end = 3,
  introns=list(c(2,2)),
  )
gggenomes(genes=f0) +
  geom_gene(position="pile") + theme_bw()

Currently produces a 0-length intron between 2 and 3. Should, however produce a 1bp intron covering pos 2.

Fixed in ef25576

f0 <- tibble(
  seq_id="a",
  start=1,
  end = 3,
  strand = c("+", "-"),
  geom_id = c("a1", "a2"),
  type = "CDS",
  introns=list(c(2,2)),
  )

g0 <- read_gff3("data-raw/foo.gff")

gggenomes(genes=bind_rows(f0, g0)) +
  geom_gene(position="pile") + theme_bw()
