* Fix attaching to a process
- e.g. omnitrace -p <PID>
* Update /proc/sys/kernel/yama/ptrace_scope in CI
* Query /proc/sys/kernel/yama/ptrace_scope
* Use AUTHOR_WARNING instead of WARNING for ptrace_scope
* Remove reliance on MPI_Comm_rank
- read /proc/<PID>/tasks/<PID>/children of parent process to deduce the rank
- Old format relied on user calling MPI_Comm_rank(MPI_COMM_WORLD, ...)
- if MPI_Comm_rank called with subcommunicators only, multiple ranks would write to same file
* Tweak mpi example

* Fix the main library stop routine for timemory
- the main pop_timemory function was popping too many calls
- this primarily affected recursive calls
