This adopts the Attr rework for the --add-xticklabel and
--add-yticklabel flags.
Sort of.
These require a bit of special behavior to make work, but should at
least be externally consistent with the other Attr flags.
Instead of assigning to by-field groups, --add-xticklabel/yticklabel
assign to the relevant x/y coord:
$ ./scripts/plotmpl.py \
--add-xticklabel='0=zero' \
--add-yticklabel='100=one-hundred'
The real power comes from our % modifiers. As a special case,
--add-xticklabel/yticklabel can reference the special x/y field, which
represents the current x/y coord:
$ ./scripts/plotmpl.py --y2 --yticks=5 --add-yticklabel='%(y)d KiB'
Combined with format specifiers, this allows for quite a bit:
$ ./scripts/plotmpl.py --y2 --yticks=5 --add-yticklabel='0x%(y)04x'
---
Note that plot.py only shows the min/max x/yticks, so plot.py only
accepts indexed --add-xticklabel/yticklabels, and will error if the
assigning variant is used.
