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

> 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.
