Added wrapper methods to the relaxation curve-fitting specific code for the new C modules.

These allow the parameter numpy array from minfx to be converted into a Python list prior to sending
it into the C module.

Removed numpy from the relaxation curve-fitting C module code.

This now expects Python lists as arguments. This should help with incompatibilities between
different Python versions, as this seems to be due to the numpy C interface. See for example

Decreased the accuracy of the PDC reading system test, as the PDC data is not accurate to 7 places.

The R1 value and error are now being read directly from the PDC file.

Fix for the PDC reading system tests, the data now matches the new PDC files.

Fix for the pdc.read() back-end for reading NOE data out of the new PDC files.

The PDC NOE conversion script is now taking the data directly from the PDC file.

Updated the Bruker PDC files to the newest versions.

These are taken from the task #7180 (https://gna.org/task/?7180) attached by Peter Neidig as file
#12537, file #12538, and file #12539.

Created a special list-like structure for spin specific data.
