DevTools Network tool should be able to import NetLog files, as it does for HAR files #4

The idea is: the DevTools Network tool already allows importing HAR files (which you can capture in a number of ways: from DevTools, or puppeteer, or others), and it would be good if it also allowed importing NetLog JSON files.

You can read more from Eric himself about NetLog here: https://textslashplain.com/2020/04/08/analyzing-network-traffic-logs-netlog-json/

You can capture NetLog files from a chromium-based browser by going to about:net-export.

As context: Netlog JSON files have higher fidelity than what HAR import/export offers, and as a consequence getting a Netlog is often preferable to getting a HAR file. However, visualizing HAR files can be easier/more convenient than visualizing Netlogs, especially as a part of initial analysis (e.g. so you know which URLRequests to examine using the NetLog viewer tool).

If we could enable the F12 Net tab to import Netlog JSON files, we could make analysis of such files simpler.
