Up to now only unit enums were supported. Add support for tuple and
struct enums, which can deserialize the following enum
enum VideoMode {
Fullscreen,
Window(u32, u32),
Remote { host: String },
}
from the following inputs:
mode=fullscreen
mode=window[640,480]
mode=remote[host=workstation]
This allows us to stop using flattened or dedicated enums for parsing and also
results in a less ambiguous syntax for these cases.

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.
