Derived types also renamed from "checked" to "guarded" to avoid confusion with check()
Remove "Invalid()" static method. The coding style compliant "GetInvalid()" is too confusing (it sounds like it might be !IsValid()), just use the default ctor.
GetValue() -> GetChecked() with user-specified default value. This is like Get() but with a check(IsValid()) in front (to make sure results are always defined, even in non-checked builds).
Add natvis for TGuardedSignedInt
Various small cleanups: constants const->constexpr, simplify from-int ctor
Only allow arithmetic ops with maching SignedType
Move to ImageCore for now

- Ported the new DDS import code from UTextureFactory to Interchange.
- Added the option to only parse the header in FDDSFile.
- Added support for texture cube arrays and volume textures.
- Dump warnings and errors in the log at the end of the import.

FLinearColor ctor from FColor is mainly three table lookups, make it inline and move to the header.
Quantize, QuantizeFloor, QuantizeRound are similarly trivial, now inline.
Move Clamp01 to FColor as static method so it's namespaced; rename to Clamp01NansTo0 to explain why it's not just FMath::Clamp to [0,1]
SSE2-ified FLinearColor::ToFColorSRGB for x86 targets, bitwise exact same results as before for all input floats (tested exhaustively, test included)
Don't want to make ToFColorSRGB inline, it's a bit large for that, but make an array version that does multiple at once. Mainly try to avoid doing a cross-DLL call per pixel for large batches.
Switch ImageCore Linear->sRGB conv to use array version.
FLinearColor R,G,B,A members union'd with "deprecated" RGBA[] array, Component() updated to use it (matching recent fix for FVector)
ImageCore vector loads from FLinearColors updated to use &Component(0) which gives &RGBA[0], pointer to a 4-elem array
Add tests to UnrealMathTest.cpp to verify that sRGB<->Linear and UNORM<->Linear conversions behave as expected, plus the separate ColorConversionHeavy test that does the exhaustive equivalence check between the SSE2 ToFColorSRGB() and reference (warning: takes a while)
