Heyo, I see that my NomadNet is clearing old announces and maxes out at 256. I'd love to be able to increase this. I'm unsure if this is the right place to make feature requests, please direct me somewhere else if not :)

FYI I suck at programming, someone should probably fix this up a bit and maybe contribute it

that being said, here's a patch I wrote

(if anyone wants to use this, dedicated to the public domain under CC0. I prefer to remain anonymous)

PS: I tested it and it seems to work, but it might have gaping holes I haven't noticed. quadruple check this before applying it to your nomadnet

here's a slightly better version of that patch:

```

I removed that debug log I added and ensured the announce length is at least positive

sweet thx! Would be great to have this implemented upstream but I can't find information on how to make contributions :/

I have this planned already in the codebase for my Web UI fork so if that gets accepted upstream it will be in base NomadNet
