Python Package: Rename mode switch to dtype to select datatype. Simplify interface log_get_record. Have lustre records include OSTs. Add library version check.
Some updates streamlining the interface and a bugfix:
- Rename mode switch to dtype to select datatype (numpy, dict, pandas). E.g., log_get_record(log, 'POSIX', dtype='pandas')
- Simplify interface log_get_record. Deprecates log_get_posix_record, etc.
- Include version check to warn about library incompatability.
Fix:
- Lustre records did not unpack list of OSTs.
