[Bug] Incorrect display of oxidation numbers when using Roman numbers in superscript

[svanterwingen]

Describe the bug
When using Roman numerals as superscripts to denote oxidation states, there is a weird behavior which puts a "+" in string mode, but not in content mode:

To Reproduce

#ce("Cu^II") vs. #ce[Cu^II]

Expected behavior

In both cases there should not be a '+' placed.

Good luck! I am just reporting stuff I find to let you know, do not hurry :)

Ah nice I think it's because some part of the parsing for Fe+2 is still active even when using Roman numerals, I'll fix it.
