Replayed Tachyon flamegraphs report unknown efficiency as 100%

Bug report

Bug description:

Binary profiles do not store error or missed-sample statistics, but replayed flamegraphs display them as perfect values.

python -m profiling.sampling run --binary -o profile.bin demo.py
python -m profiling.sampling replay --flamegraph -o profile.html profile.bin

The sidebar shows 100% sampling efficiency and 0% missed samples. These values are unknown during replay and should not be displayed as measured results.

CPython versions tested on:

3.16

Operating systems tested on:
