[ruby/ipaddr] ntop: Measure address size in bytes
`IPAddr.ntop` takes the binary representation of an IP address, whose length should be 4 or 16 *bytes* (not characters/codepoints). The current implementation accepts strings in any encoding, but for some values in non-BINARY encoding, it fails proper length check and raises an `AddressFamilyError`. Since passing strings in a multibyte encoding has never worked correctly for years, this makes it an explicit error with an `InvalidAddressError`. Fixes: https://.com/ruby/ipaddr/issues/56 https://.com/ruby/ipaddr/commit/a33fd14d4a
