Allow optional structs which members all have default values to have their values omitted. This is convenient when we want to specify a flag that can take optional extra arguments.

Serde deserializer from key=value strings
A lightweight serde deserializer for strings containing key-value pairs separated by commas, as commonly found in command-line parameters.
Say your program takes a command-line option of the form:
--foo type=bar,active,nb_threads=8
This crate provides a from_key_values function that deserializes these key-values into a
configuration structure. Since it uses serde, the same configuration structure can also be created
from any other supported source (such as a TOML or YAML configuration file) that uses the same keys.
Integration with the argh command-line parser is also provided via
the argh_derive feature.
See the inline documentation for examples and more details.
