by default next/image provides an attribute quality to change default quality=75 value and unfortunately has no global configuration for this value except loaderFile
@unpic/react/nextjs has a killer advantage, because it can dynamically render local images, which next.js still can't do,
but it can't change quality either globally or on each image through attributes
loaderFile also does not affect unpic image

so my suggestion is to implement the quality attribute to at least recreate the functionality of next/image
