Add profiling capabilities to GBasis

[msricher]

Add profiling capabilities to GBasis. By running py.test [FILES] --profile or py.test [FILES] --profile-svg, the test that is ran will be profiled and profile information (.prof) and optionally a heat map in .svg format will be generated in prof/.

pip install .[test] will now pull in the required libraries for this to work.

@msricher is this ready to merge? I'm not sure if you got an offline review from @marco-2023 or @FarnazH or @leila-pujal or @gabrielasd ?

Hi @PaulWAyers, on my side I didn't get to review this. I vaguely remember that maybe the goal was to do a profiling of Gbasis to know where the bottlenecks are without adding this feature into Gbasis, but it's been some time since we worked on this so I could very well be mixing things.
