fix(tiktok): Force H.264 (avc) codec to prevent missing audio and RAM exhaustion in WSL

Browse Source 
- Updated `get_format_string` in `__init__.py` to prioritize `[vcodec*=avc]`.
- This ensures yt-dlp fetches pre-mixed video and audio formats for TikTok, instead of downloading `bytevc1` (H.265) streams which lack audio or require heavy FFmpeg merges that cause Out-of-Memory errors in WSL.

# 🚀 FIX: Prioridad Absoluta al archivo PRE-MEZCLADO (Video + Audio unidos de fábrica).
# Evita que FFmpeg colapse la RAM intentando fusionar pistas separadas de TikTok.
# 🚀 FIX DEFINITIVO TIKTOK/AUDIO: Forzar contenedor H.264 (avc) pre-mezclado.
# TikTok sirve el formato 'bytevc1' a menudo sin pista de audio o ilegible.
# Al exigir 'vcodec*=avc', obligamos a yt-dlp a bajar el MP4 estándar que SÍ trae el audio integrado,
# evitando además el colapso de RAM por fusión de pistas en FFmpeg.
