fix: iOS Safari crash fix

[mazshakibaii]

When using Safari on iOS, an empty packet is sent within the first few seconds of connecting. This causes the connection to close. By checking that e.data.size > 0, we only send packets with data to the Deepgram API, preventing this from happening.

This has been an outstanding problem on discord and on github:
