OMNITRACE_ROCM_SMI_METRICS (#331)

* OMNITRACE_ROCM_SMI_METRICS

- configuration variable OMNITRACE_ROCM_SMI_METRICS for specifying which rocm-smi metrics to collect
- auto-disable metric collection when rsmi_dev_X_get returns RSMI_STATUS_NOT_SUPPORTED

* Bump version to 1.11.1

* Python formatting

* Update python/libpyomnitrace.cpp

- fix usage of substr (ignored return value)

* Update python/gui/source/gui.py

- Fix E721
  - do not compare types, for exact checks use `is` / `is not`, for instance checks use `isinstance()`
