ByteBufferBackedBinary serialization is broken

[asfimport]

While working on logical types for parquet-avro, I updated the FromStringBinary to work with a CharSequence instead of a String, which broke TestFilterApiMethods#testSerializable. The underlying problem is that when the buffer-backed binary is deserialized, length and offset are not initialized so the buffer is correct but the apparent length of the binary is 0.

Fixed in PR #305. Luckily, no other Binary classes failed the new serialization test.
