Need to update parameters for KSDT XC functional
The current parameters for the KSDT parameterisation within
lda_xc_ksdt.c are outdated.
In https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.120.076401, Karasiev references a paper that discovered some rare unphysical negative entropies under certain conditions, and gives the new corrected parameterisation in Table S2 of the Supplementary Material.
The current, outdated, parameters implemented in LibXC are those found in the original KSDT paper https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.112.076403.
It should just be as simple as changing the values of the parameters for the KSDT parameterisation. The GDSMFB parameterisation is unaffected.
