Get compression scheme of ktx2Texture

[Galo32]

Hello, there is a way to check which compression scheme (ETC1S/UASTC) was used to encode a ktxTexture2 object from ktxlib?
I was reading https://github.com/KhronosGroup/3D-Formats-Guidelines/blob/main/KTXDeveloperGuide.md#ktx-container-format and it presents different desired VkFormats (when available) to decode to, depending on the compression scheme used.

There are a couple of ways.

1. You can use ktxTexture2_GetColorModel_e and compare the result against the KHR_DF_MODEL_ETC1S and KHR_DF_MODEL_UASTC. Those enums are defined in khr_df.h.
2. If you are only interested if it is ETC1S, you can check the supercompressionScheme. ETC1S always uses scheme 1, BasisLZ.
