#149 introduced a minor regression which included duplicates for the Unbound generation script.
While this does not have a technical impact it may cause confusion for users, this PR will ignore duplicate entries.
This change leverages #130 and also applies this to the dnsmasq script.
As it currently stands both generation scripts (unbound and dnsmasq) have a condition where a domain will be skipped if it fuzzy matches a domain already parsed that is higher in the CDN domain list.
For example the latter of the below two samples would never be added.
8793ce1531/steam.txt (L20)8793ce1531/steam.txt (L29)
I've also taken the liberty to sort the output of said scripts for readability and troubleshooting purposes.
Closes#130.
