/**
 * Takes a folder, in which it gets subfolders representing materials. data.json files are taken from those subfolders.
 * This will create a materials.csv file with the shader information and the material id.
 * If zip is to be created, the textures are collected and added to a zip file.
 * This expects a structure that is already working in the RLCS.
 * Texture files will not be reused, but every material has the copy of the texture file. This is the same as in RuAd.
 *
 * @param materialsFolderPath the path to the folder, in which the material_external_id/data.json files are located
 * @param fi * @param regex * @param regexPattern
 * @param textures 'no' or 'zip' whether to extract only the materials.csv with id and shading or if a zip should be created
 * @param contentFolderAbsolutePath optional absolute path to the content folder, needed if textures are included and @ content prefix is used
