patterns: Add support for KTX 1.0 textures (#451)
* Commit patterns I've collected - AppleSingle/AppleDouble pattern, used for macOS resource forks. - MAME CHD file format, currently only supports v5. - KEX Engine proprietary TARC format, used by various Nightdive games. * Add to README * Add pattern for KTX 1.0 file * Use import, add reference ktx file * Add to README
