  7. (take 2) fix var types / compiler warnings 

    - in `fprintf`s
- `_stackprof.interval` is an int
- `timestamp_delta` as `int64_t`
   - but doing the same with `_stackprof.raw_timestamp_deltas` makes it segfault!

  10. try to fix 'hanging' test in CI - 

    it appears that at 1μs, performance hit of profiling causes test to take >10s to run, and time out.
try at 10μs instead.
