Added a test to check the decoded image with the result from dxt-js. The result of dxt-js was written to json file in advance.
I made the spread of the expected result in +-1 value. The difference of a pixel, even if all its colors will be shifted by 1 - not noticeable.
Difference in 1 unit can occur due to divisions and rounding of values, when calculating the palette.
Tests for dxt1, dxt3, dxt5.
dxt-js does not support dxt2, dxt4, these encoding methods differ from dxt3 and dxt4 only by multiplication of pixel colors by alpha, there is no such parameter in dxt-js.
