[FIX] fields: verify image resolution on create/write

Before this commit, if `max_width` and `max_height` are 0, the image would not
be opened by Pillow at all (to gain a bit of CPU) however this was actually a
bad idea in this case because then we don't ensure the given value is actually a
valid image when we save it, only later at display we notice it and it crashes.

This optimization only made sense when `image_process` is called many times,
from the route displaying images every time a visitor is requesting an image,
for example. It doesn't really have an impact for one time operations such as
creating/writing.

So when size parameters are 0, which is the default, another parameter must be
passed to `image_process` to ensure image validity, and `verify_resolution` is
actually built for this, as it does the minimal amount of processing:
- loading the image
- making sure it is valid
- and ensuring the resolution is not completely crazy (`IMAGE_MAX_RESOLUTION`).
It doesn't alter the original image if no other operation was requested.
