eeshow/: simple caching of sheets

We only reuse previous sheets if ...

- they have no sub-sheets, and
- all the libraries are identical.

This reduces the -N-150 time from 8.3 s (caching only libraries) to 4.3 s.

Since we only need to know whether there are sub-sheets, but not what
exactly they are, we can also partially undo the previous commit,
