Support parsing negative numbers with a specified radix as e.g. `-0xff00` instead of `0x-ff00`. This is a potentially breaking change but I don't believe anyone made use of the former syntax anyway. The new number parser has the nice side-effect of removing some extra code, and also signaling parsing errors more accurately, so that's an added bonus. On the other hand we lose the distinction between "invalid number" and "expected number", but that distinction was dubious anyway so losing it is for the better IMHO.

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.
