Strings size limitation is a mess, since we host XMP strings in DB. XMP has no
size limitation.

Anyway, some strings has make and model are generally short (255 char is
enough)

But some other as all string dedicated to IPTC-core can be long, as
descriptions for photograph agencies workflow. Please take a care about.
