Add Support for Longer Speech Length

Seamless works well for short speech input, but even M4T Large v2 struggles with speech beyond 2 minutes, causing degraded accuracy and performance.

Yeah. Long-form doesn't work at all. I end up with OOM on an 80GB H100 GPU. Why is this called "Streaming" at all if it can't do anything that actually does require streaming?
