reflected_parameters should use lightfuzz standard_probe

[liquidsec]

lightfuzz standard_probe knows how to deal with various parameter types, not just GET parameters like the current request function does. Once this change is in place, we will be able to see reflected parameters from each type

#2168 Achieves the goal of this, although ultimately it did not make sense to re-use the standard_probe from lightfuzz as the use case was sufficiently divergent to justify unique functions.
