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')

[iPurya]

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

Oh, makes sense.

Hi! I’d like to implement optional HEIC/HEIF support via pillow-heif (registering the Pillow plugin). I’ll add a small path-based interception in image_to_string to load .heic/.heif with Pillow and pass a temp PNG to Tesseract, plus tests and docs. Okay to proceed?

I think you meant to comment on #363, which is about HEIC support? The issue you commented on is about image URLs and not related to HEIC.
