Python environment dependencies for 2P_reader

Install with: pip install -r requirements.txt

Notes:

- viewer.py uses napari which requires a Qt backend; the [all] extra pulls a working Qt stack.

- reader.py forces matplotlib's TkAgg backend; ensure system Tk is available on your OS (macOS usually has it via python-tk / tk).
