Feature request: Add receive timeout to UDP AniDBSocketHandler

[LordFlashmeow]

VERSION INFORMATION

Server Version:
Daily

DESCRIPTION

_aniDBSocket.ReceiveFromAsync can hang on network disconnect, blocking the UDP worker. Attempting to ctrl-c the server is ineffective, because the logout process tries to send a UDP logout message (which gets blocked behind the frozen socket).

ShokoServer/Shoko.Server/Providers/AniDB/UDP/AniDBSocketHandler.cs

Line 75 in 289021d

var receivedResult = await _aniDBSocket.ReceiveFromAsync(result, SocketFlags.None, temp);

#1122 implements the timeouts, which seems to fix the issue when a connection is dropped (or the server wakes up from sleep). However, 598 UNKNOWN COMMAND responses show up instead, but at least the server is ctrl-cable now.

@fearnlj01, tagged you since you made the initial fix, is this something we can also address?

I know how to fix it, theoretically. I just need time
