Fixes Weather Soundspam(And Crash) (#1501)

# Description

Pretty simple fix, just tell the weather system "If there's already a
weather sound playing, stop.". I have infact tested this, and verified
that this fix does work.

Fixes Simple-Station/Einstein-Engines#1285

# Changelog

:cl:
- fix: Fixed a crash caused by Weather System creating millions of
sounds.

(cherry picked from commit 28415f18a1cb2549e9faa29c1ce66889dc0ef323)
