Feature: Filter by process binary path

[Ciantic]

Filter is able to filter by command line, but not by command path.

For example I'd like to filter running processes with "projects" in the path which would match all the binaries in my ~/projects.

I know that smem is capable of doing that by default when using -P.

I find myself needing that as I test multiple binaries in one path, with no common process name.
