Fix for the relax_disp.r2eff_read_spin user function.

The offsets are now converted to ppm prior to finding the R2eff/R1rho key.

Large redesign of the R2eff/R1rho data structures.

The five indices {Ei, Si, Mi, Oi, Di} for the experiment type, the spins of the cluster, the
magnetic field strengths, the pulse offsets, and the dispersion points (nu_CPMG or nu1) respectively
are now much better defined. The Oi dimension is new and allows for support of R1rho-type data
whereby both different offsets and different spin-lock field strengths. Previously only one or the
other was supported, but not both together. The offset information is now included as part of the
spin R2eff/R1rho key, even if not set.

To support this, the specific_analyses.relax_disp.disp_data module now has the new functions
loop_exp_frq_offset(), loop_exp_frq_offset_point(), loop_exp_frq_offset_point_time(),
loop_frq_offset(), loop_frq_offset_point_key(), loop_offset(), and loop_offset_point(). All of the
{Ei, Si, Mi, Oi, Di} dispersion indices throughout the source tree have been changed to ei, si, mi,
oi, and di respectively. And the time index ti has also been introduced. These changes hugely
simplify the code.

Implemented GUI test, which caches the bug.

Fix for bug #21076, (https://gna.org/bugs/?21076) - When loading a multi-spectra NMRPipe seriesTab file through the GUI, several Error messages occur.

Fix for loading a seriesTab formatted intensity, and getting the ID for the following GUI elements.

Fix for bug #21076, (https://gna.org/bugs/?21076) - When loading a multi-spectra NMRPipe seriesTab file through the GUI, several Error messages occur.

The relax_disp.r2eff_read_spin user function now can handle offset data in the file.

If the new offset_col argument is set and disp_point_col is not, then the file being read can
contain the spin-lock offset information rather than the spin-lock field strength values. This is
only for R1rho-type data.

The relax_disp.spin_lock_offset user function now uses the lib.nmr module.

This is for converting between ppm and rad/s units.

Created the new lib.nmr relax library module.

This currently has a few simple functions for converting between ppm units and Hertz or rad/s units.

Small fix for the documentation of the relax_disp.r2eff_read* user functions.

This is for both relax_disp.r2eff_read and relax_disp.r2eff_read_spin.

Added some R1rho data from Dmitry Korzhnev's Fyn SH3 domain.

This originates from the cpmg_fit software and is published data.

Small comment fix.
