How to convert the old input parameters for oscillators for HREELS calculations to the ones for the yaml input files.

Lorentz

ωTO_new	= ωTO_old
QK_new	= QK_old
γnew	= λold * ωTO_old = osc[3] * osc[1]

ωTO_old:	osc[1]
QK_old:	osc[2]
λold:		osc[3]

Drude

ωP_new	= ωP_old / sqrt(epsinf)
γnew	= λold * ωP_old

ωP_old:	osc[1]
λold:		osc[3]

Note: old osc[2] is -1 or negative to indicate Drude term. Its value is not further used as a parameter in the calculations.
