qa-physics: parse README.json for cook-dependent settings

[c-dilks]

Run dependent code in monitorRead.groovy is not really sustainable. Instead, consider parsing the README.json file, typically included with cooked data. For example:

{
  "recharge": false,
  "helflip": false,
}

Be careful though, after doing this, this QA code may not "catch" cases where a setting is inconsistent with prior cooks; for example, we don't notice the helicity sign convention is changed until far downstream physics analysis asymmetries flip sign...

It may be better to keep this run-dependent code and just add a warning, to catch cases when some setting differs from expectation / prior cooks.
