* Fix to #3465. Prevent the, resaving of duplicate images if overwrite not specified
This is a fix to #3465
Adds function compare_image_hash to do a sha256 hash comparison between an uploaded image and existing images with matching file names.
This changes the behavior so that only images having the same filename that are actually different are saved to input, existing images are instead now opened instead of resaved with increment.
Currently, exact duplicates with the same filename are resave saved with an incremented filename in the format:
<filename> (n).ext
with the code:
```
while os.path.exists(filepath):
filename = f"{split[0]} ({i}){split[1]}"
filepath = os.path.join(full_output_folder, filename)
i += 1
```
This commit changes this to:
```
while os.path.exists(filepath):
if compare_image_hash(filepath, image):
image_is_duplicate = True
break
filename = f"{split[0]} ({i}){split[1]}"
filepath = os.path.join(full_output_folder, filename)
i += 1
```
a check for if image_is_duplicate = False is done before saving the file.
Currently, if you load the same image of a cat named cat.jpg into the LoadImage node 3 times, you will get 3 new files in your input folder with incremented file names.
With this change, you will now only have the single copy of cat.jpg, that will be re-opened instead of re-saved.
However if you load 3 different images of cats named cat.jpg, you will get the expected behavior of having:
cat.jpg
cat (1).jpg
cat (2).jpg
This saves space and clutter. After checking my own input folder, I have 800+ images that are duplicates that were resaved with incremented file names amounting to more than 5GB of duplicated data.

* To reduce bandwidth traffic in a remote environment, a lossy compression-based preview mode is provided for displaying simple visualizations in node-based widgets.
* Added 'preview=[image format]' option to the '/view' API.
* Updated node to use preview for displaying images as widgets.
* Excluded preview usage in the open image, save image, mask editor where the original data is required.
* Made preview_format parameterizable for extensibility.
* default preview format changed: jpeg -> webp
* Support advanced preview_format option.
- grayscale option for visual debugging
- quality option for aggressive reducing
L?;format;quality?
ex)
jpeg => rgb, jpeg, quality 90
L;webp;80 => grayscale, webp, quality 80
L;png => grayscale, png, quality 90
webp;50 => rgb, webp, quality 50
* move comment
* * add settings for preview_format
* default value is ''(= don't reencode)
