Support for uploading multiple photos to Array Field

[lucabfelix]

Hello!!!

Could you add support for uploading more than one photo at a time in ArrayFiled? Currently, by clicking on the field, I can only upload one photo at a time.

On my phone, it's more complicated, because I can't open a window to drag multiple photos.

When we are dealing with many images this feature becomes very useful and important.

Finally i got some time to work on this project. I'm finishing PR #213 and, then, i work on this.

Hi @lucabfelix! Sorry for the long wait time, released on 1.1.0 on Pypi:

can select multiple images on dialog or can drop multiple images on picker. If more images than limit are used (see #216), the others are ignored.

@EduardoJM Thank you very much for the work. The widget is getting better and better :)
