g.parser: Missing support G_OPT_F_FORMAT in python %option

[gulshan-123]

Currently using below gives the unexpected warning:

# %option G_OPT_F_FORMAT
# % guisection: Formatting
# %end

WARNING: Bug in UI description. Missing option key
WARNING: Bug in UI description. Description for option <?> missing
WARNING: Bug in UI description. Missing option key
WARNING: Bug in UI description. Description for option <?> missing 

This was detected as a part of #7051 (comment).

The reason was G_OPT_F_FORMAT is missing in standard_option.c.

NOTE: The C code is not affected because, those directly use G_define_standard_option(), but for parsing python %option, we use define_standard_option which compares the string defined in the STD_OPT_STRINGS (with same index as enum declared in gis.h).

I'm not sure which type of tests should I add so that missing to add may be avoided in future?
Or should we plan to merge the two things: arrays and enums (is this possible?)?
Ideas please...

Looks in principle good to me. Just one minur comment...
The failing tests are likely unrelated...

There is likely a Python tool which should probably have it since the time this was introduced. Is there?

Does not seem so. See: https://github.com/search?q=repo%3AOSGeo%2Fgrass%20path%3A*.py%20language%3APython%20G_OPT_F_FORMAT&type=code
vs.

db.univar, v.db.univar, and t.rast.list could have used it: https://github.com/search?q=repo%3AOSGeo%2Fgrass%20path%3A*.py%20language%3APython%20%22key:%20format%22&type=code

...should have it already, but it does not is what I meant to say.

[wenzeslaus]

I think we should have it in these tools and this PR is the place to do it.

[gulshan-123]

Thank you!
I have now added #option G_OPT_F_FORMAT in db.univar, v.db.univar and t.rast.list.
Also Added the format option description in t.rast.list just for completeness

Looks good to go! Thanks!

Adressed.
