title: Manually set numbering of sphinx-proof
body: <p>I've tried around numbering my sections in my jupyter book and each different try leads to different outcomes of how my theorems, definitions etc. are numbered in my different pages. I have chosen the following numbering system for my book</p>
  <p>1 Chapter 1<br />
  1.1 Section 1<br />
  1.1.1 Subsection 1<br />
  1.1.2 Subsection 2</p>
  <p>I want my theorems, definitions etc. to be labeled Theorem 1.1.1, Definition 1.1.2 and so on through my Section 1, but what Sphinx-proof does is to label them as Theorem 1.1.1.1 and Definition 1.1.1.2 (if both are under Subsection 1). Is there a workaround of this or is there some way of manually numbering the theorems, definitions etc.?</p>
  <p>I know it should be possible through an extension. I've not tried writing an extension before since I'm new on this executablebook and in generel coding-adventure. So any help is much appreciated.</p>
