Add 0x15 as valid 0x07 value for BEAST

[jakub-jedrusiak]

I have 2x32GB Kingston FURY BEAST RAM cards with part number KF560C30BBAK2-64. I tried to use your script with their RGB lights but model verification failed. All blocks were OK except block 5 (0x07) where my value was 0x15, while the only values expected for BEAST were 0x10 and 0x12. After confirming ten times that my RAM really is FURY BEAST, I took the risk and modified your script to include 0x15 as a valid value. And it worked, for which I'm incredibly grateful, because I searched for a long time. Thus I share my change for your consideration. I believe it should also help with #34.
