 * Added the following trace categories for Chrome that now is used by default when you turn on the timeline: 'disabled-by-default-devtools.timeline.frame', 'disabled-by-default-devtools.timeline.invalidationTracking','loading', 'latencyInfo' - done in [#2086](https://github.com/sitespeedio/browsertime/pull/2086).
 * Added a simple Loaf-script to get the 10 largest loaf. Lets iterate over the script and see how we can get the most useful information from it [#2087](https://github.com/sitespeedio/browsertime/pull/2087).
