The variant convertFromMemoizedJson trait did already do something similar, calling "convertFromJson" if the memoized version is not avilable. Now the function also "decides" based on the passed data itself.
* Random number generation was faulty, as we have to use RAND_MAX and not INT_MAX
* fixed CTestAircraftSituation::testSetRotateUpPitch, we need to use a defined front function otherwise it can be randomly outside range
* adjusted performance unit test a bit, as the value vary a lot
Ref T261
* the timestamp of status message was not copied, so every time a status message was sorted or otherwise assigned the ts got lost or wrongly assigned.
* this meant the log messages were in wrong order, leading to very confusing results in the log screen or file.
* also added new timestamp formatter
* new function "BlackMisc::CVariant displayRole(const PQ &pq) const" which can be used if the PQ is already available
* removed "IndexEnableGndFlag" as this is actually part of FSD network settings
* renamed to "isForcingVtolInterpolation"
* adjusted interpolator, and UI for setup
* min/max ground distance, also added in situation list
* use model's vtol/CG info
* improved scenery deviation guessing
* adjusted interpolator scenery deviation handling
* this is an optimization, it would work without that, but there are numerous calculations in interpolation which are faster and easier to debug in the same unit
* PQ switch unit functions use "const &PQUnit"
* return interpolation results parts/situation in one step
* base class init for each interpolation step, less redundant code
* removed old interpolation/parts function
* adjusted unit tests and simulator objects (such as SimObject)
* using interface IInterpolant, renamed to CInterpolant for concrete implmentation
* CInterpolatorPBH has itws own file now, is included
* linear interpolator only re-calculates interpolant when needed (same as spline interpolator)
* made the interface a "real" interface and provided implementation as CCLientProvider
* aligned some function names with networl context
* network context "impl" also implements ICLientProvider
