Review Comment:
This is where I am having mixed feelings about this change. The case
statement goes over JSON as well which is not a storedType. JSON is logical
type and uses STRING as stored type.
https://github.com/apache/pinot/blob/master/pinot-spi/src/main/java/org/apache/pinot/spi/data/FieldSpec.java#L393
`JSON(STRING, false, false),`
Partly I think the change is right because when reading values out of
forward index reader, we should do it based on the `storedType` that dictates
how the bytes are stored. In that case, code like below should not reference
JSON or any other logical type. So, additional cleanup is also needed but want
to make sure no assumptions made in the code about logical type v/s storedType
are broken.
