process.hrtime not available in browser

[DenisCarriere]

process.hrtime is not a valid function in the browser.

Have this ever been tested in the browser? Tests are passing fine in NodeJS.

Might be handy to set up a simple /docs folder with an index.html and a browser friendly build to simply test this library in the browser. Here's a "minimalistic" approach I've been doing for some of my libraries https://github.com/DenisCarriere/slippy-tile/tree/master/docs.

I can send a PR to include a simple Rollup config that builds the bundle, let me know.

For this type of debugging/timings, you could look into including debug for your internal testing/debugging.
