  Fix clear compression stats

  ## Description
    The aim of this merge request is to fix the
    `drive::clearCompressionStats()` method which deleted all log metrics
    with log select on page 0x00 (aka reset all metrics).
    The following changes are introduced:
      * For **IBM and LTO drives**: We are selectively clearing only the
      * compression statistics (pages 0x38, 0x32 equivalently)
      * For **Oracle and MHVTL drives**: Wa are making compression
      * statistics stateful, by accumulating values and subtracting on
      * each flush
    Moreover, we are piggybacking a fix for overflowing
    mountTotal{Read,Write}BytesProcessed
    (drive::xx::getTape{Read,Write}Errors) by bumping up the container map
    in 64-bit value

  ## Testing
    The results of the changes were tested against IBM and Oracle
    drives.
    More specifically, we attempted to write 40 randomly generated files
    of 2GB in size with the previous CASTOR version (2.1.16-9), extracted
    the compression metrics and compared
