byte array
                 Key: CARBONDATA-2402
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-2402

Currently in carbondata, while converting object to byte array, it use 8 byte 
space for int and short datatype, which cause memory wasted.

Code can be found in `CarbonUtil.{{getValueAsBytes` }}and 
`DataTypeUtil.{{getMeasureObjectFromDataType`}}
