Firmament Packet Fix

What?

Disables Firmament's ModAnnouncer feature, which sends the server a list of every mod you are using.

Why?

This "feature" of Firmament has the potential to send a packet too large for the server to handle. My modpack alone already hits about 1/3 the max size, and I have seen (and used) larger modpacks than mine. Additionally, I consider this to be a massive privacy breach, and also completely useless in the first place. This packet is not required for any features to work, Firmament still functions as normal.
