                lockbit black blob decoding POC
              
          
    Blobs in lockbit black are decoded similar to BlackMatter but with a new LCG based on 64 bit
The init seed for the sample I REd was at the start of .pdata
POC decoding, pretty quick and dirty due to time constraints

    return(a1 * a2)
