Fixes issues from PR 276

[bennybp]

This PR is meant to fix some issues introduced in #276

• References seemed to be incorrect (and grimme2018 doesn't exist). I think mTZVP should be brandenburg2018a, and mTZVPP should be grimme2021a
• Harden turbomole parsing a bit with regex
• The basis set data for def2-mtzvpp-ri seems to be inconsistent. The data in the BSE does not match the authoritative source file at all
• The reference data for def2-mtzvp-rij has syntax errors (there is a line with 3 but no exponents/coefficients
• The rij basis isn't referenced as the an aux basis

I think the orbital basis was mistakenly copied as the rij basis as well @susilehtola

Welp, looks like doing work in a hurry isn't bug-free 😜

The def2-mtzvp-rij and def2-mtzvpp-rij basis sets seem to be identical. So I removed the def2-mtzvp-rij basis and just made def2-mtzvpp-rij the aux basis for def2-mtzvp.
