WIP: Track parameter dimensions

This MR increases the local track parameter dimensions to 6 and the global track parameter dimensions to 8. The additional parameter represents the timing. Additionally, this MR get rid of hard-coded dimension numbers and replaces them by a variable. Note: At the current state, this MR just shows all the parts of the code that need to be replaced/expanded in order to describe the timing. As soon as this is implemented, it will be re-included into the code and polished.
