Cowboy style 24-bit int to ieee float conversion

/*
Insano 24-bit integer to ieee float conversion by JoaCHIP. Winners do drugs. Here be dragons.
Assumptions: Your FPU uses ieee float and your CPU uses reverse "intel" byte order.
Expected output:

    -8388605 ---> -1.000000
    -6710884 ---> -0.800000
    -5033163 ---> -0.600000
    -3355442 ---> -0.400000
    -1677721 ---> -0.200000
    +0000000 ---> +0.000000
    +1677721 ---> +0.200000
    +3355442 ---> +0.400000
    +5033163 ---> +0.600000
    +6710884 ---> +0.800000
    +8388605 ---> +1.000000
