Stack filtering

[xmo-odoo]

When using cprofile as a CLI, there can be lots of intermediate or ancillary noise in the profile. The ability to filter stacks become very useful then.

It's doable using —format=log and flamegraph.pl as the flamegraph log is a list of stacks so a simple grep works, but that means not getting the improvements of flameprof's "native" SVG (especially getting the reverse graph alongside the normal one).
