Fix lightfuzz deserialization Error Resolution false positives

[liquidsec]

Transient 500 errors were sometimes causing false positives with the lightfuzz serialization submodule. Fix was to add confirmation step, and also a final last resort which looks at the completely ridiculous outcome of having multiple language families all report deserialization, which is not possible. A bit of a hack, but an extremely effective proxy for catching false positives.
