Remove LHCb mdf writer compression by default
Remove LHCb MDF writer compression by default, since IOSvc
does not currently support compressed inputs and also because there is already compression internally to the "DstData" raw banks (which dominate when no detector raw banks are written out). See #163 (closed). By default, the compression level is currently set to 2.
