Allows saving name of used command in a field of result target.
Helpful when command callbacks are stored in a table with names as keys
or when they are in submodules of some namespace.
Example:
local parser = argparse():command_target("command")
-- Add commands...
local args = parser:parse()
require("namespace." .. args.command).run(args)
