added exclude cli parameter to exclude files by pattern

[wallaroo]

hi,
i added a cli parameter 'exclude' to confugure some filename patterns from parsing.
the default is set to ['index.js'] because is a common use to organize components in indexed namespaces
Es.

/package.json
/app.js
/components/
/components/namespace1/index.js
/components/namespace1/Component1.js
/components/namespace1/Component2.js

where index.js is:

export Component1 from './Component1'
export Component2 from './Component2'

and app.js imports these components with:
import {Component1, Component2} from './components/namespace1'

i know that someone use the pattern /components/ComponentName/index.js (i don't like this) so... maybe is better to set [] as default...

That's great, thank you! Yeah, I think we should leave the default empty, otherwise this would be a breaking change.

Definitely looking forward to this being added. Any chance this can get added into the next release?

@dptoot , @wallaroo just needs to remove the default value and this should be good to go 😃

sorry for the late React...ion ;-)
