Flamegraph colouring 🎨

[cyriltovena]

Right now the only colouring we support for flamegraph is based on the self value of the node.

But we would like to offer more options and so we want to know if the community has more ideas.

To kick the tire here are some other options we've been thinking:

• Language specific (Detect language and external libraries with different colours)
• Random (Just make it look nice)
• Total samples observed (not the sum of samples values but the number of time the sample was observed)
