Allow equals sign to be omitted for named arguments

[dantownsend]

You currently have to use an equals sign when passing in a named argument:

python main.py my_command --desc="some message"

This can lead to confusion when people omit it, using this format instead:

python main.py my_command --desc "some message"

It would be good to support both formats.

@akankshasainics Yes, that would be good. It might be quite a challenging issue though!
