Support maxFiles on Dropzone

[rodolphoasb]

Currently, our Dropzone component doesn't support the maxFiles prop that is supported by the react-dropzone package.

Not sure but maybe this is just a type thing that we would need to add.

I'll add this feature in next minor release

Hey, @rtivital! Sorry to bother... Any update on this one?

[rtivital]

It will be added in next release (minor or major whichever comes out next).
