[Feature] Add Percentage of Tolerance against Missing Articles

[BakasuraRCE]

Hi,

In practice, when you are trying to corroborate if an NZB is alive, it is enough to allow a maximum percentage of missing items (10% is the unwritten standard?) That does not belong to the Par2 files, after that limit and having corroborated that The Par2 are alive, you could consider an NZB as dead and stop the check.

In summary, could you implement options to establish a percentage of tolerance if you know that the NZB contains recovery files to a percentage x?

Thanks.

I don't think it has sense cause nzbCheck only checks the header of Usenet articles.
Nowadays it seems that especially for 2021, some backbones have the headers but not the bodies of the article. (cf this reddit thread)
which means you end up with nzbCheckt detecting more than 50% less missing articles than in realliy, which means according to nzbCheck a post could be recovered, but when you actually download it it won't be...
