Detailed description of a problem

The vanilla minecraft client sends one arm swing packet and one block_dig packet with status 0 when mining blocks that have a dig time of 0. But Mineflayer also sends an extra block_dig packet with status 2 meaning finished digging.
The finish digging packet is only send in the vanilla client when the block can not be mined instantly.

Expected behavior

Only send a stop digging packet when the blocks dig time is not 0.
