title: How to search a buffer for a numeric range which contains a given value
body: <p>I have a buffer which holds some lldb output which contains a lot of address ranges like <code>[0x00007fff60489000-0x00007fff604c0000)</code>.</p>
  
  <p>Given an address (in hex as well), how would I search for a range which contains that address? I assume this will need some custom elisp code.</p>
