Implements proper voice activity detection with:
- 200ms hold period after audio drops below threshold to prevent choppy cutoffs
- Terminator packet (end_bit=true) when speech ends to signal stream completion
- TransmitState enum to track transmission state across frames
This ensures other Mumble clients receive proper end-of-speech signaling
for clean audio termination and correct "talking" indicator behavior.

Pretty simple, if the average amplitude is under a certain value clear
out the buffer! The value I chose (.001) was an arbitrary value I got
from printf debugging. I was able to show that this worked pretty well
on the desktop session. Hopefully we'll add this to the settings page at
some point.
