Valid particles are causing parsing error

[MicahGale]

Describe the bug

This is a follow-on from #669, as it actually contains two bugs.

Valid particles: (Positive|Negative) Sigma baryon, (+|-), are not being parsed properly

To Reproduce

A short code snippet of what you have ran. Please change or remove any specific values or anything that can't be public. For example:

import montepy
montepy.Cell("1 0 2 imp:+ 1")
montepy.Cell("1 0 2 imp:- 1")

Error Message (if any)

This produces the following error (note they are nearly identical so only one error is shown:
