vvoigtabs, zvvoigtabs: voigt absorption line with widths in km/s

A voigt absorption line with line widths in km/s as a multiplicative model. The zvvoigtabs variant includes redshift as a parameter.

$$M(E) = exp(-d*v(E))$$

where $v(E)$ is the voigt line shape (see vvoigt for details), and the parameters are:

par1	$E_l$, line energy in keV.
par2	$\sigma$, gaussian line width (sigma) in km/s.
par3	$\gamma$, lorentz line width (FWHM) in km/s.
par4	$d$, line depth in keV.

For zvvoigtabs the parameters are:

par1	$E_l$, line energy in keV.
par2	$\sigma$, gaussian line width (sigma) in km/s.
par3	$\gamma$, lorentz line width (FWHM) in km/s.
par4	$d$, line depth in keV.
par5	$z$, redshift
