Research and document other network throttling profiles

[phuedx]

Ofcom published results of their 2014 and 2015 (late Q4, 2014) studies into 4G and 3G bandwidth and latency in the UK here and here respectively.

Google Chrome/Chromium's network throttling profiles now have download and upload bandwidth configured separately, thus µDL should configure download and upload bandwidth separately too.

I'll track implementing the new network profiles in a separate ticket since, in practice, it's blocked on #7.

Here's an example profiles.yaml file from the Measuring mobile broadband performance in the UK (02/04/15) report:

profiles:
  - name: 4G (UK)
    bandwidth: # (Mbit/s)
      download: 14.7
      upload: 13.6
  - round_trip_time: 53.1 # (ms)

  - name: 3G (UK)
    bandwidth:
      download: 5.9
      upload: 1.6
    round_trip_time: 63.5
