Use Two way algorithm to optimize ByteBufUtil.indexOf() method
Motivation:
ByteBufUtil.indexOf can be inefficient for substring search on
ByteBuf, in terms of algorithm complexity (O(needle.readableBytes * haystack.readableBytes)), consider using the Two Way algorithm to optimize the ByteBufUtil.indexOf() method
Modification:
Use the Two Way algorithm to optimize ByteBufUtil.indexOf() method.
Result:
The performance of the ByteBufUtil.indexOf() method is higher than the original implementation
