Reduce lightfuzz serial submodule False Positives

[liquidsec]

Should begin to reduce false positives as described in #2170

Fully remediating these FPs will likely be an iterative process due to the nature of the detection algorithm.

Also changing behavior regarding original values, previously any parameter with an original value was ignored. Now, they will be checked, but only after surviving a validation function checking to see if they are valid 64 or hex (or raw php object). Added tests for all relevant functionality.
