add name() function, to explictly set the name

[TooTallNate]

For --help/-h only at the moment.

So that you can do something like this, when the
CLI name doesn't match the entry point file name:

import args from 'args';
import { name } from './package.json';

args.name(name);

…

Meh. I guess I can use usageFilter for this…

@TooTallNate What do you think? Should we still add .name() in addition? If so, please fix the tests (just some linting errors).

[TooTallNate]

Actually... instead of introducing a new function, we can do it in the .parse(argv, options) options object. So something like:

args.parse(process.argv, { name: 'foo' });

Thoughts?

3 LOC change at this point 💃

Probably squash when ready to merge.

Great way to handle it! Thx 😊

Oh... And we also need to add it to the config list in the readme.
