Move PulsarParameterPy wrapper into CWInPy
For easier development, it is worth moving the PulsarParameterPy
class from LALPulsar into CWInPy.
One thing to add into the class is storing of the raw par file text rather than reconstructing it. This means that parameters that are not currently parsed by the XLALPulsarParameters
object, but which might be used by Tempo2 are still stored.
