Subject: [PATCH] Apply the sonpy platform marker to the ced and all extras

sonpy 1.9.12 only publishes wheels for Windows, and for Linux and macOS
on Python 3.14. Elsewhere `pip install neo[ced]` fell back to the sonpy
source distribution. Use the marker already present in the `test` extra
for `ced` and `all`, so those platforms install nothing and CedRawIO
raises its ImportError on first use.

Make that ImportError name the platform constraint, as the CedRawIO
docstring already stated, and update the docstring to cover both extras.

Follow-up to #1891.
