Version 5.5.0

• added collection types for dual IPv4/v6 tries and for dual IPv4/v6 associative tries, issue #103
• trie performance improvements for all trie operations
• added shortestPrefixMatch trie methods
• added enumerate methods, the inverse of the increment methods, to find the position of an address in a subnet, or to find the distance between two addresses
• added an increment method accepting a BigInteger argument to IPv6Address and IPv6AddressSection
• added the ability to construct an IPv6Address from two longs
• added replace methods with address section parameter to address classes
• added overlaps methods to check for overlapping subnets, and for checking sequential range overlap with a subnet
• added floor/lower/ceiling/higher methods to the address trie types, these methods previously accessible only from trie sets
• added the extraneous digits IPv4 parsing option allow_inet_aton_extraneous_digits, issue #105.
• includes the fix to invalid radix argument infinite loop, issue #118
