Converts the FlameGraph format (stackcollapse-*) to the Spall format.
Spall is an extremely fast profiler by Colin Davidson. For optimal file size and load times, Spall has a proprietary binary format. This tool produces files in that format.
The FlameGraph format was created for Brendan Gregg's FlameGraph tool. A wide variety of stackcollapse-* scripts are available for different languages, e.g. stackcollapse-perf, stackcollapse-chrome-tracing, and stackcollapse-xdebug. This tool converts the collapsed format to Spall, so it should be compatible with any of those tools.
Go 1.19 or higher is required. Make sure that $GOBIN or $HOME/go/bin is on your PATH.
