rjgtoys.cli: Command-line tool components

rjgtoys.cli provides support for building CLI tools on top of the standard argparse parser library.

It supports:

• Creation of ‘command languages’ in which diverse operations are given names that are short phrases, such as ‘make tea’;

• Modularisation of parser construction, so that commands that share options can share the code to parse and process them;

• New options for processing command line arguments, such as comma-separated lists, and set-valued options;

• Assistance with producing help.
