Offload sampling data (#190)

Browse Source 
- update timemory submodule
  - support for load/save of ring_buffers
  - new output keys, e.g. `%nid%`
  - sampling allocator offloading data
- writing sampling data to temporary file
- new advanced config option `OMNITRACE_USE_TEMPORARY_FILES`
- new advanced config option `OMNITRACE_TMPDIR`
- SIGINT signal (i.e. `Ctrl+C`) triggers backtrace + finalization
  - this behavior is common to other profilers

* update output.md docs

* Update omnitrace-avail output keys handling

* update writing metadata

* str format in perfetto_counter_track

* Fix fail regex for mpi-example

* config updates

- OMNITRACE_USE_TEMPORARY_FILES
- OMNITRACE_TMPDIR
- Enable finalization with SIGINT
- code supporting creation of temp files

* sampling offloading to temporary file

* Disable creation of empty temporary files when off

| `%args_hash%` | MD5 sum of `%args%` |
