Add image_url_to_string

[iPurya]

add image_url_to_string function to use image direct link instead filename.
tesseract 5.1 already have this feature.

If tesseract 5.1 supports it, you can just try to use:

pytesseract.image_to_string('https://url')

this method tries to open the file and when im using url it raise error.

Oh, makes sense.
