517be93cab [skottie-wasm-perf] Command line application to measure perf
Uses puppeteer to bring up Chrome headless and then calls
skottie-wasm-perf-html with endpoints for canvaskit.js, canvaskit.wasm,
and the target lottie file.

cb5ed84589 [skottie-wasm-perf] Date.now() has millisecs precision, we need microsecs
Uses performance.now() which should be within 5us.
performance.now() was increased to be within 100us in https://chromium-review.googlesource.com/c/chromium/src/+/853505 but this has been undone since then with https://cs.chromium.org/chromium/src/third_party/blink/renderer/core/timing/time_clamper.h?l=26

Verified that the version of puppeteer we will use (1.17.0) uses crrev.com/662092 from puppeteer's package.json that revision is from May/2019 so it does include the 5us change.
