Disk Cache Format changed to V3

[RandomNameUser]

Describe the problem
The disk cache format has changed to a new version in the latest Chrome release. The current pyhindsight version cannot read it at all.

There is some documentation about the format at https://www.chromium.org/developers/design-documents/network-stack/disk-cache/disk-cache-v3/, even though that's probably not enough to fix the implementation. :(
