Please describe the changes in your PR. If it is addressing an issue, please reference that as well.

The ai-coustics integration (AICFilter, AICQuailVADAnalyzer, AICTytoObserver) moves to aic-sdk 3.4.0, which uses core SDK 0.26.0. That core only loads model files of version 8.

• AICQuailVADAnalyzer. Defaults to vad-ms-2.1-xxs-16khz. We renamed vad-2.1-xxs-16khz to that ID, and the old ID has no version 8 file.
• AICTytoObserver. Defaults to Tyto 1.2 (tyto-1.2-l-16khz). tyto-1.1-l-16khz has no version 8 file. The score fields are the same.
• Examples. The three ai-coustics voice examples use Voice Focus 2.3 (quail-vf-2.3-l-16khz) in place of 2.2.

Breaking Changes

• Code that passes model_id for a model with no version 8 file now fails to download it, with "missing compatible version v8". Examples are quail-vf-2.2-*, tyto-1.1-l-16khz and vad-2.1-xxs-16khz. Change to a current ID, such as quail-vf-2.3-l-16khz. https://artifacts.ai-coustics.io/ lists the available models.
