Update IpInterface::inRange()

[zanbaldwin]

• Fix bug when comparing IPv6 and IPv4-embedded addresses (incorrect network addresses compared).
• Will now throw InvalidCidrException on an invalid CIDR, instead of just returning false.
• Will now throw WrongVersionException on comparing two IPs of differing byte-length (IPv4 vs IPv6/IPv4-embedded).
• Helper methods in Multi now correctly detect IPv4 according to embedding strategy and CIDR.

Do not merge until after #76 (update AbstractIP::isSameByteLength() to use Darsyn\IP\Util\MbString).

Unsure whether this is a breaking change or not :thinking:

Technically an exception is thrown where one wasn't before, but only on invalid inputs that would thrown an exception for all similar methods.
