This PR cuts the extraction dependency on Low* KrmlLib for extraction of Pulse code to C or Rust via Karamel.
So far Pulse extraction was relying on
C._zero_for_derefto extract access to references usingBufLoadfrom the Karamel AST: using this index instead of 0 makes Karamel turn an array access into a pointer access. ButC._zero_for_derefis defined in KrmlLib, which is written in Low*.This PR replaces
C._zero_for_derefwith a Pulse-specific definition,Pulse.Lib.Pervasives._zero_for_deref, so that verification no longer depends on Low* KrmlLib.
