Feature Request: new method `choose_files()` for uploading multiple files

[Abdelgha-4]

The same logic as choose_file() but allows for a list of paths that are then sent to the uploader element (one shot joined by \n, or one by one depending on browser/uploader?).

This will be a safe and efficient way instead of doing multiple calls or calling send_keys from the user code.

That could be done in a loop via the existing choose_file() method:

for file_path in file_paths:
    self.choose_file('input[type="file"]', file_path)

Also, often after uploading a file, one generally has to click another button to complete some process.
