This PR aims to fix `ClassCastException` when reading avro decimal type in

which causes scan to fail.

java -jar core/target/orc-benchmarks-core-*-uber.jar scan data
```
```java
Exception in thread "main" java.lang.ClassCastException: class
java.nio.HeapByteBuffer cannot be cast to class java.lang.Double
(java.nio.HeapByteBuffer and java.lang.Double are in module java.base of loader
'bootstrap')
