Adding the digi parameter files for tof v20a.

See merge request !1

These are copies of v16e.

We don't want to have files with dos CRLF line endings in the repository,
so we test if any of the changed files has this file type.

run 831 parameters, others to follow soon

A new geometry with the tag v20a, containing changed z positions.
This commit updates the parameter directories accordingly.

Since the tof geometries haven't changed but only the file format
no new parameters were produced but a symlink to the old were added.
