GHSA-Q2QQ-HMJ6-3WPP hickory-proto vulnerable to CPU exhaustion during message encoding due to O(n²) name compression

During message encoding, hickory-proto's BinEncoder stores pointers to labels that are candidates for name compression in a Vec. The name compression logic then searches for matches with a linear scan. A malicious message with many records can both introduce many candidate labels, and invoke this...
