Enable pytest-asyncio tests in CI (#92)

* Set asyncio_mode="auto" in pytest.ini config

Xref https://pytest-asyncio.readthedocs.io/en/latest/reference/configuration.html#asyncio-mode

* Refactor contents of test_cog.py into a proper unit test

Put everything in an `async def test_cog_s3` function, with assertions checking different metadata attributes.

* Uncomment `uv run pytest` in .github/workflows/test-python.yml

* Add `--color=yes`flag to force GitHub Actions logs to have color

Xref pytest-dev/pytest#7443

* Ruff format

* Remove timing assertions

* Bump astral-sh/setup-uv from 3 to 6

Bumps [astral-sh/setup-uv](https://github.com/astral-sh/setup-uv) from 3 to 6.
- [Release notes](https://github.com/astral-sh/setup-uv/releases)
- [Commits](astral-sh/setup-uv@v3...v6)

* Remove `uv sync` part

* Bump pytest-asyncio from 0.24.0 to 0.26.0

Bumps [pytest-asyncio](https://github.com/pytest-dev/pytest-asyncio) from 0.24.0 to 0.26.0.
- [Release notes](https://github.com/pytest-dev/pytest-asyncio/releases)
- [Commits](pytest-dev/pytest-asyncio@v0.24.0...v0.26.0)

Also set asyncio_default_fixture_loop_scope="function" following pytest-dev/pytest-asyncio#924 (comment)

* Revert "Remove `uv sync` part"

This reverts commit 638d602.

* Typo geoindex-rs -> async-tiff

* Add back `--no-project` flag to `uv run` commands

Partially undo bfb3a43
