Scalene decorator

Is your feature request related to a problem? Please describe.

At this moment we can only run Scalene on the entire application, which makes profiling a time consuming process. It would be nice to have more fine-grained control over the functionality that should be profiled.

Describe the solution you’d like

Create a decorator that can be used to activate the profiler for specific functions / classes.

@scalene
def func_under_test():
    ...

Next create an environment variable that contains a list with all the functions that should be profiled

SCALENE_PROFILE_FUNCTIONS=func_under_test,another_func_under_test

Describe alternatives you’ve considered Write a separate script that can be run specific functionality.

Hey @emeryberger, on a similar note to the decorator, any plans to make it possible to run Scalene programmatically from within the code like cProfile.

While this is not the requested @scalene operator, it fits with established practice by other profilers, and I think addresses this issue. Please feel free to re-open if not!
