[Before](https://github.com/leanprover/lean4/files/14772220/oi.pdf) and [after](https://github.com/leanprover/lean4/files/14772226/oi2.pdf). This gets `ByteArray`, `String.Extra`, `ToString.Macro` and `RCases` out of the imports of `omega`. I'd hoped to get `Array.Subarray` too, but it's tangled up in the list literal syntax. Further progress could come from make `split` use available `Decidable` instances, so we could pull out `Classical` (and possibly some of `PropLemmas`).
