Audit all debouncing rules

[fmarier]

It looks like several rules in the debounce.json are unsupported or broken in subtle ways (see #869 for example) and while the main concern is webcompat, these could also lead to more serious problems because we are redirecting to different URLs than the intended ones.

We should therefore audit all of the existing rules to ensure that they are redirecting to the intended destination URL (and that they are using the tightest possible hostname).

All of the rules added since the initial import I looked at have example URLs (thank you @ryanbr !): https://github.com/brave/adblock-lists/pulls?page=1&q=is:pr+is:closed+label:Debounce

The rules pulled in from external sources will need a bit more work since we need to find examples of them in the wild (e.g. by googling for them) before we can review the URL pattern and determine the URL encoding used.

Here are the results of auditing all of the existing debounce rules:

• Removed: 66 rules (59 from external import)
• Changed: 37 rules (mostly tighter URL patterns)
• Added: 10 rules (new bouncers discovered while investigating existing ones)

List of PRs:

• Add several missing bouncers found in external lists #902
• Delete broken imported rules #905
• Tighten the patterns on shareasale bouncers. #906

There is now documentation for this feature including how to write rules (and what edge cases to look out for).
