Feature Request: Proper Support for Multiple Metrics in @nsight.analyze.kernel #8

Hi, I'd like to request proper support for specifying multiple metrics in the @nsight.analyze.kernel decorator. Currently, when providing a comma-separated list of metrics, the data aggregation doesn't work correctly.

Being able to collect multiple related metrics in a single profiling run is essential for performance analysis. For example, comparing both load and store operations (smsp__sass_inst_executed_op_shared_ld.sum and smsp__sass_inst_executed_op_shared_st.sum) in one run is much more convenient than running separate profiling sessions for each metric.

Users currently need to run separate profiling sessions for each metric, which is cumbersome and time-consuming:

@nsight.analyze.kernel(runs=1, metric="smsp__sass_inst_executed_op_shared_ld.sum")
def profile1(...): ...

@nsight.analyze.kernel(runs=1, metric="smsp__sass_inst_executed_op_shared_st.sum")
def profile2(...): ...

It'll be convenient if all the metrics could be separated by commas:

@nsight.analyze.kernel(runs=1, metric="smsp__sass_inst_executed_op_shared_ld.sum,smsp__sass_inst_executed_op_shared_st.sum")
def profile1(...): ...
