vapor pressure option (#6)

• vapor pressure option added (can only be used with COSMO-RS in censo)

How to use crenso for a vapor pressure calculation:
Option: -vp (alpbsolvent_name, no file extension) (dielectric constant) (dcosmors potential file: only the solvent name e.g. thf not thf_25.pot)

The information of the solvent parameters will be written to a file called  'same_solvents.json' which has the same construction as the file
~/.censo_assets/censo_solvents.json. If a user created same_solvents.json file is in the source calculation directory this file will be copied
and used for the following calculation.

    {
      "same":{
        "cosmors": ["same", "same"],
        "dcosmors": [null, "thf"],
        "xtb": [null, "thf"],
        "cpcm": [null, null],
        "smd": [null, null],
        "DC": 7.8
      }
    }

• temperature now changeable from crenso
• general ouput improvements
