    jpeg: Increase memory limit for loading image data
    
    As fix for security issue #205 when loading image data the memory size
    was limited to 100 MB. That seemed like a good threshold. For larger
    images, from around 18 megapixels (MP) and up though not for all such
    images, this threshold was too low. Increasing the threshold too 300 MB
    seems to work better and lets larger images load.
    
    Fixes #216.
