  1. New operator MDR, for refactoring floating point arrays using MGARD's… 

    … new MDR extension.

 - Only works with BP5 for now since BP5 deserializer had to be modified for reading with accuracy
 - Use mgard cmake flag MGARD_ENABLE_MDR to set ADIOS2_HAVE_MGARD_MDR flag and build refactor operator conditionally
 - Added Accuracy struct to adios types (error, norm, and rel|abs flag)
 - Set/GetAccuracy() functions to Variable, VariableBase and Operator classes.
 - BP5 deserializer now prepares the operator with accuracy before calling Decompress().
 - bpls new option --error "double,double|inf,rel|abs" added.
 - Add tests for MDR operator and Accuracy default behavior (for all operators)
 - Add rounding error constants adios2::ops::mdr::DOUBLE_ROUNDING_ERROR_LIMIT and FLOAT_ROUNDING_ERROR_LIMIT,
      beacuse GetAccuracy() is limited by rounding errors in MDR
