+/* bcdec.h - v0.94
+   provides functions to decompress blocks of BC compressed images
+   written by Sergii "iOrange" Kudlai in 2022
+   This library does not allocate memory and is trying to use as less stack as possible
+   The library was never optimized specifically for speed but for the overall size
+   it has zero external dependencies and is not using any runtime functions
+   Supported BC formats:
+   BC1 (also known as DXT1) + it's "binary alpha" variant BC1A (DXT1A)
+   BC2 (also known as DXT3)
+   BC3 (also known as DXT5)
+   BC4 (also known as ATI1N)
+   BC5 (also known as ATI2N)
+   BC6H (HDR format)
+   BC7
+   BC1/BC2/BC3/BC7 are expected to decompress into 4*4 RGBA blocks 8bit per component (32bit pixel)
