Typo in realtime code in calculate_audio_length_ms function

[nbondoux]

Describe the bug

The function calculate_audio_length_ms defined in realtime/_util.py has an issue:

def calculate_audio_length_ms(format: RealtimeAudioFormat | None, audio_bytes: bytes) -> float:
 if format and isinstance(format, str) and format.startswith("g711"):
 return (len(audio_bytes) / 8000) * 1000
 return (len(audio_bytes) / 24 / 2) * 1000

if the audio is g711, it will answer a number of milllisecond; however, if the audio is 16bits 24kHz PCM, it will answer a number of microseconds.
