> An Avro decimal logical type annotates Avro bytes or fixed types.
> Current Row to Avro conversion is limited to bytes type and in addition hardcodes precision to MAX_INT and scale to 0. 
> I have attached a patch that adds support for decimal bytes and fixed types.
> I could think of 2 possible ways to solve this:
>  # Change Row decimal type to a logical type
>  # Use Beam field options to pass additional metadata required to serialize decimals
> I felt that overhauling Beam schema types might not be a good idea. Instead I went with option 2.
> Passes ./gradlew check
