A small tweak, but this resolves some confusing interactions between
subplot subplots and regular subplots.
Consider:
./scripts/plot.py test.csv -xx \
--subplot=" \
-ya \
--subplot-below=\" \
-yab\"" \
--subplot-right=" \
-yb \
--subplot-below=\" \
-ybb\""
You would normally expect -yab and -ybb to end up side-by-side. But
because regular subplots were parsed fully before subplot subplots, -yab
confusingly ended up beneath the sum of -ya + (-yb + -ybb).
The small tweak of prioritizing subplot subplots fixes this, and
results in the expected 2x2 grid of plots.
