Improve FindPatternSIMD and GetVirtualMethodTable Allow searching for multiple occurrences, the main reason for this addition is that some RTTI object locators reference 2 (or more) VFTables, the ConVar class is a good example., where we have 2 separate VFTables, one implementing ConCommandBase (which implements its own IConVar), the other implementing just IConVar for ConVar (2 VMT pointers in one class).

uintptr_t GetModuleBase(void) const;
Refactored BuildPropStaticFrustumCullMap (see description) Redacted most code to only perform operation to obtain studiohdr and staticprop material (read only operation, function does not modify memory used by the original 'v_BuildPropStaticFrustumCullMap()' implementation!) The new function checks if pointer is within bounds (must stay within .data memory), if this isn't the case, the 'batch' is considered corrupt and function call to 'v_BuildPropStaticFrustumCullMap' won't proceed (note that the loop checks all bodygroups/LOD's of a model, it is possible that one doesn't have corrupt data, but a model where only one of its submeshes culls properly in the level is too much effort to fix as this function is based of disassembled output of the engine implementation, which in it self, comes with its own limitations). For a better implementation we should proceed fully rebuilding the function (see commented function body). The current and only problem with this is that it doesn't compute cull data properly (see bsplib.cpp line '222').
