Added comment about the Erratum

```math

\begin{aligned}

c_e      &= 0.054 \,\text{ns}\,\text{cm}^{-2} \\

c_e      &= 0.54 \,\text{ns}\,\text{cm}^{-2} \\

\kappa_e &= -0.62 \\

\\

c_h      &= 0.0427 \,\text{ns}\,\text{cm}^{-2} \\

for electrons and holes, respectively.

The parameters for electrons are taken from \[[@Mandic]\], for measurements at a temperature of $`T = -20 \,\text{°C}`$, and

the results extrapolated to $`T = -30 \,\text{°C}`$. A scaling from electrons to holes was performed based on the default

the results extrapolated to $`T = -30 \,\text{°C}`$.

The c_e has been updated accordingly based on the erratum \[[@MandicErratum]\].

A scaling from electrons to holes was performed based on the default

values in Weightfield2 \[[@weightfield2]\].

This model can be selected in the configuration file via the parameter `trapping_model = "mandic"`.
