Images (optimization and printing filesize)

[DexterCoaster]

Upon reading one of a similar feature request i needed (cookbok printing or batch printing #4912), I went on and manually downloaded every single recipe but noticed the image filesize on the exported PDF does not correspond to the Mealie base upload. Mealie outputs 2,5 mb PDFs while recipes with no image output 37 kb. Seems like there is a conversion on mealie's side that makes the filesize bigger instead of using the original image.

This is my workflow: compress the image using a custom script down to MAX_MEGAPIXELS=1.8 QUALITY=40 on .webp
this way I get 50-130 kB images and keep storage low. More than enough quality for miniatures and small image printing.
But also mealie keeps duplicates, one original, one low res (mine already is) and one high res. Making the filesize bigger and reducing precious server data storage.

So as a summary, improvement ideas:
-Batch printing
-Image optimization (customisable through the admin profile)
-Printing image output revision

Great job to all contributors! Really quite impressed on the functionality of this recipe keeper!
