Jihong MA updated CARBONDATA-607:
---------------------------------
Description:
Rewrite ValueCompressionHolder class as a base class for compressing or
uncompressing numeric data for measurement column chunk.
refactor all sub-classes under
org.apache.carbondata.core.datastorage.store.compression.decimal.*
org.apache.carbondata.core.datastorage.store.compression.nonDecimal.*
org.apache.carbondata.core.datastorage.store.compression.none.*
org.apache.carbondata.core.datastorage.store.compression.type.*
as part of the work, also fix a performance bug to avoid creating unnecessary
