Title: ORIGEN 2 Transmuter

This adds a transmuter class based on ORIGEN v2.2. Right now you need to supply your own TAPE9.INP file for the transmuter to work. It also adds a `base_tape9.inp` file that was generated using the `tape9` cli. However, this file does not work with ORIGEN just yet. However, it is a first cut. This PR also adds a lot of robustness features to the writing of TAPE9 files. This broke roundtrip-ability, but I think it is worth it.
