Live captions demo: fails to download and build during installation

[guynich]

I've hit this failure on several linux platforms: Ubuntu 22.04.2, Ubuntu 24.04.2 and Debian 12.8 when running this command.

uv pip install -r moonshine/demo/moonshine-onnx/requirements.txt

  help: `llvmlite` (v0.36.0) was included because `useful-moonshine-onnx` (v20241016) depends on `librosa` (v0.10.2.post1)
        which depends on `numba` (v0.53.1) which depends on `llvmlite`

A mitigation is to install numba package before running the command.

uv pip install numba
uv pip install -r moonshine/demo/moonshine-onnx/requirements.txt

This mitigation is added in #71.
