Scan all bunny CDN cnames and check if the domain hosts Fathom's javascript file

Hello, while most of the Fathom tracking is already blocked in https://github.com/AdguardTeam/cname-trackers/blob/master/trackers/fathom.txt a few scripts pass through because they use a other CNAME domain.

Examples:

`prefinery.com` -> `electric-eighten.b-cdn.net`
`steadybit.com` -> `type-thirtyseven.b-cdn.net`
`meinsmartplan.de` -> `gorgeous-easy.b-cdn.net`

Example for the script: `prefinery.com` -> `https://glowing-van.prefinery.com/script.js` But the list only contains `ant.prefinery.com`

I don’t know if it can be fixed because `b-cdn.net` get widely used
