New description:
Add `atoms()`, `coatoms()`, and `doubly_irreducibles()` to `LatticePoset`.
Add missing functions, like `join_irreducibles()`, to index of functions.
Do this after #19123 gets positive review and gets into beta.
Other things:
- Check documentation of `breadth()`, stupid way to express
`BooleanLattice(4)`.
