 A thin python wrapper for the nvToolsExt (NVTX) library, using pybind11. This
 wrapper is meant to be as thin as possible -- so only provides minimal support.
 Currently supported features are:
-1. NVTX markers: `nvtxRangePushA` and `nvtxRangePop`
-2. Function decorator: `PyNVTX.mark`
-3. Automatic decorator generation `PyNVTX.mark_all_methods(<class name>)`
