Replace TachyPy audio backends with TachyAudio

[iancharest]

Summary

• Replace TachyPy-owned sounddevice/dummy audio backends with a thin tachyaudio.OutputStream wrapper
• Add tachyaudio>=0.2.0b1 as the base audio dependency and remove sounddevice extras/docs
• Raise TachyPy's Python requirement to >=3.10 to match TachyAudio
• Update audio tests to mock TachyAudio streams instead of sounddevice/dummy backends
• Bump package metadata to 0.1.17 because 0.1.16 is already published

Validation

• ./.venv/bin/pytest --cov=tachypy --cov-report=term-missing --cov-fail-under=80 -> 82 passed, 92.04% coverage
• ./.venv/bin/ruff check src tests -> passed
• ./.venv/bin/python -m sphinx -b html docs /tmp/tachypy-docs-build -> passed
• ./.venv/bin/python -m pip check -> no broken requirements
• Temporary venv install resolved tachyaudio==0.2.0b1 from PyPI and imported tachypy.Audio successfully

Pull request overview

This PR migrates TachyPy’s Audio utility away from TachyPy-owned sounddevice/dummy backends to a thin wrapper around tachyaudio.OutputStream, aligning packaging, docs, and tests with the new dependency and raising the minimum Python version to match TachyAudio.

Changes:

• Replace internal audio backend implementations with a tachyaudio.OutputStream-backed scheduler.
• Update tests to mock tachyaudio streams instead of sounddevice/dummy backends.
• Update packaging/docs/CI for tachyaudio>=0.2.0b1, Python >=3.10, and remove TACHYPY_AUDIO_BACKEND=dummy CI configuration.
