> The spec says there are three keys in metadata blocks - schema, count and _codec_. But
the code in DataFileWriter adds schema, count and _sync_. The sync field is used by the DataFileReader.
We need to do the following:
>    - Add the key sync in the specification.
>    - Either drop the key codec in the specification or add code to support codec in DataFileReader/DataFileWriter.
If we decide to have codec, we need to also publish  in the spec the list of supported codecs
with their names to use in the metadata block.
