New XRF implementation

[beteva]

• Change the AbstractXRFSpectrum class:
  • snake case method names.
  • remove unnecessary methods.
  • use the standard HardwareObjectState states and emit stateChanged only.
• Change the xrf queue model to call the new methods and to use the strateChanged signal only
• Add tests

WIP as testing not finished yet.

will try to test this in the beamline next week, on a quick look it looks good!

Thanks @meguiraun. For information it works on the ESRF beamlines.

ok, looks fine to me then. We can follow up with a PR for the signal documentation and perhaps eventually something with a model instead of the dictionary for the ISPyB values
