Plugin channel max length is 16 when it should be 20
A while ago (unfortunately I don't have the exact version, but this change was present in 1.10.0), the max length for plugin channel names was increased to 20. However, liteloader still enforces the old limit of 16. This is a problem because other systems allow the longer length, and thus they can't be sent.
This is a 2-line change: ServerPluginChannels on line 233, and ClientPluginChannelsClient on line 92.
I would have submitted a PR for this, but it seems like I'm unable to fork the repo ("– Limit reached Your project limit is 0 projects! Please contact your administrator to increase it ")
