Support `console_scripts`

I tried running scalene on one of my CLI programs. It didn’t go well:

• I tried running python -m scalene --help; this does not work
• I generally write my CLI programs to launch console_scripts entry points, which doesn’t seem supported.
• I added an explicit if __name__ == "__main__" to my CLI program and scalene no longer aborted; however it also didn’t produce any output beyond what my program already produced.

Any guidance on proper usage would be appreciated.

I have a new pull request for support console_scripts. 😸

Updated to provide conventional command-line help and output redirection.

 % python3 -m scalene --help                                   
usage: scalene [-h] [-o OUTFILE] prog

Scalene: a high-precision CPU and memory profiler.
https://github.com/emeryberger/scalene

    for CPU profiling only:
  % python -m scalene yourprogram.py
    for CPU and memory profiling (Mac OS X):
  % DYLD_INSERT_LIBRARIES=$PWD/libscalene.dylib PYTHONMALLOC=malloc python -m scalene yourprogram.py
    for CPU and memory profiling (Linux):
  % LD_PRELOAD=$PWD/libscalene.dylib PYTHONMALLOC=malloc python -m scalene yourprogram.py

positional arguments:
  prog                  program to be profiled

optional arguments:
  -h, --help            show this help message and exit
  -o OUTFILE, --outfile OUTFILE
                        file to hold profiler output (default: stdout)

Will work on the other issue described here.
