> Use CRC tables to speed up galoisFieldMultiply in CrcUtil

> CrcUtil.galoisFieldMultiply(p, q, m) supports multiplying two polynomials p,
> q modulo any modulus polynomial m over GF(2). Since the method is used for
> CRC calculations, the modulus polynomial m is restricted to either the
> GZIP_POLYNOMIAL or the CASTAGNOLI_POLYNOMIAL. We may use CRC tables in
> PureJavaCrc32/PureJavaCrc32C to speed up the computation.
