Custom Nodes Upload File Button

[NikoTumi]

So I've been trying to make my first custom node and I saw load image node has a button which pops up with a choose file window. Upon 4 hours of research, I found this:

Only "image_upload" works natively ComfyUI's core only supports file upload buttons for images (via {"image_upload": True}). There is no official "file_input" or generic file upload option.

So, might I suggest we get this with the option for specific file extensions? Its easy enough to do in tkinter lib.

That's a great idea. We can name the option like {"file_upload": True, "accept_filetypes" : ["video/webm", "video/mp4", "video/mkv"]}. It would work just like image_upload -- the chosen file would be uploaded to the server and the actual value of the widget/dropdown would just be the filename.

I made a feature request:
