comparisons: add x/tools/internal/telemetry to compare against #2
Description
I just pinged @rs about the comparison work we did at https://github.com/orijtech/telemetry-perfbench and showed him the benchmarks at https://github.com/orijtech/telemetry-perfbench#benchstat-results
He let me know that we could also add our comparisons in here, so this issue is to explore adding them /cc @kirbyquerby @ianthehat. @kirbyquerby, please take a look at this issue.
