The color scheme takes either
- a raw escape sequence like "\033[33m" (pySim-read,
pySim-prog, contrib/csv-to-pgsql.py)
- a cmd2 color object (pySim-shell)
Color of cmd2 >= 3.0.0 is a StrEnum, which led to
pySim-shell warnings like
yellowWARNING: EF.DIR seems to be empty!
with a stray reset at the end.
Fixed by exclusing Enum from the raw sequence branch.
