Added

• Low-level API that gives finer control over the loading process (alternative to TextureBase.LoadBytesRoutine)
• ManagedNativeArray wrapper for efficient access of managed byte[] from C# Jobs
• Basis Universal texture (.basis) Editor import
• Support for loading any single image/layer/mipmap level of textures of any type (arrays, cubemaps, volumes)
• Support for discarding mipmap level chain (and import just one mipmap level)
• Support for importing Basis Universal texture types 2darray, 3d, video, cubemap (single images only at the moment)
• Many property getters on KtxTexture (e.g. needsTranscoding,hasAlpha,isCubemap)
• Experimental support for importing uncompressed KTX 2.0 textures (limited set of formats for now; #47)

Changed

• De-prioritized texture formats RGBA4444 and BGR565 to avoid incorrect channel usage or low quality. Transcoding to RGBA32 instead.
• Bumped minimum required Unity version to 2019.4 LTS

Fixed

• Textures with alpha channel are shown blended (with checkerboard background) in the inspector now (alphaIsTransparency is enabled; #64)
• Avoid extra memcopy of input data by using ManagedNativeArray in LoadFromStreamingAssets and LoadFromUrl
• Improved texture format usage detection (linear vs. sRGB sampling)
• Loading of native library on Linux (thanks @Blackclaws for #60)
