Relative percentage display for Console output

[Khreas]

Hello!

First of all, thanks for the great package. I discovered it recently but am already a big fan of it! 🎇

Issue #132 and issue #171 mentioned the fact that displaying percentages alongside actual timings could be interesting. The kind of percentages discussed in the two issues are not exactly the same. #171 mentioned the percentage of time a frame took to execute compared to the whole execution time while #132 mentioned the percentages of time a frame took relatively to its direct siblings.

Since I am also interested in this kind feature, I have implemented a specific processor that computes the percentage of time for a specific frame given its direct siblings. Switching to the overall execution percentage should be easy by modifying the said processor.

Plus, I modified the ConsoleRenderer and the Profiler classes by adding a parameter that controls whether those percentages should be displayed or not. Finally, I added a command line switch that would trigger the

Here's what it looks like:

I did not push the development too far (like adding that to the HTML output) for the moment to leave room for discussion, but if you think that such changes could be of any interest, I'll gladly add support to HTML / JSONRenderers!

Have a nice day 🚀

Hi @Khreas, thanks for sending this over! I personally think that percentages relative to the total as seen in #171 might be more useful. Would that suit your use case also? Additionally, I wanted to have a look at how we might generalise the renderer options so that other renderers can add options without further expanding the command line interface. So I might take a crack at this myself and see where I end up.
