Motivation for this change

I added lemmas for convenience of derivable_oo/Nyo/oy_continuous_bnd.

  • Derive continuity within corresponding interval. The relating lemma is derivable_oo_continuous_bnd_within.
  • Restrict the interval, like continuous_subspaceW
Checklist
  • added corresponding entries in CHANGELOG_UNRELEASED.md
  • added corresponding documentation in the headers

Merge policy

As a rule of thumb:

  • PRs with several commits that make sense individually and that
    all compile are preferentially merged into master.
  • PRs with disorganized commits are very likely to be squash-rebased.

These are technical lemmas but they seem needed to instrument the definitions derivable_oo_continuous_bnd, etc., so that should be fine. I have renamed the lemmas to be more idiomatic and change the hypothesis of the first one to use `[c, d] `<=` `[a, b] instead of inequalities, so that the use might use lemmas about intervals.
