Changes

Clubb timer upgrade (#1328)

* Upgrading CLUBBs timer system. Now we either can use gptl just by compiling with it, or we use a cpu_time based fallback that was designed to be a crude copy

* Giving up on using the build system to detect stale build, switching to a method that just compares timestamps on directories

* Fixing small UI bug and removing a bit of dead code in the dash app, also fixing a gptl compiling issue on mac

* Little fix for python

* Adding a bit about the new timing output in the output section of the README

* Improving print statements and disabling timing and iteration prints when debug=-1
