Decimal values from avro files matching this specification are unable to read using current avro-spark releases.

Hi @mzitnik ,

Branch is branch-3.2, but PR was not accepted.

If you are using version 3.2, you may try https://bintray.com/peter-ungvari/maven/spark-avro/3.3.0
This was released from my fork.

I don't think anybody will merge my PR anytime soon, see #276

After the project built successfully on my fork, Travis failed to download sbt api on PR in some cases:
