Philip Rideout b60518caa5 Add libs/ktxreader, rename some things to prep for KTX2.
Changes:

- Remove the strange header-only variant of libs/image
- Rename KtxBundle => Ktx1Bundle
- Move image/KtxUtility => ktxreader/Ktx1Reader
- Add unit test for Ktx1Reader and test stub for KTX2.

Notes:

- Ktx1Bundle does not depend on Filament and is used by cmgen
  and mipgen to generate KTX files.

- Ktx1Reader has a dependency on Filament and should therefore live in
  a separate library, which it now does.
