      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 compression/uncompression value holder during compression or decompression.
