greggameplayer 3b00333b0c Add return of Texture Size and Bytes Per Pixel of ASTC2D 5x5, 6x6, 8x8, 10x10 and 12x12 (#249)
* return correct size of ASTC 5x5, 6x6, 8x8, 10x10 and 12x12

* return correct Bytes Per Pixel

* Use method in order to get CompressedTextureSize

* Add Read16BptCompressedTexture method

* add Bpb integer argument
