Charge trapping Correction with a minimzer for LQ

This PR adds a new function for the LQ charge trapping correction. It works similar as the AoE or energy ctc. The function uses a minimizer to find the optimal correction to minimize the sigma of the DEP. The named tuple `vis` can be used with a new LegendMakie recipe to produce a fit of the minimizer parameter space. The old function is kept and a deprecation was added. I also changed the file structure of the lq functions, so that the lq_norm and the two ctc functions are in separate files.
