Modified parameters in the DATA/data_2level/ folder to scale the same as in the
SQD-MNP paper.

Modified input file where theta is no longer input as a complex number: the
complex part is dealt with in the main program, so theta is a real number which
is calculated from the inputs m_h and gamma_g.

Updated the comment in the input file, replacing gold_max_height with m_h

Modified src/params.f90 to take in m_h (instead of theta) as a real number.
theta is then calculated.
src/runge_mod.f90 modified to calculate Q_MNP approximately for any waveform.
The a^3 factor is also taken into account in calculation of the P_MNP.
lin_resp.sh: amongst other things, the final chi(omega) is divided by
eps_eff1=2.67777 to correspond with the paper.
Parameters input/output changed.
