E0 not allowed by Parser

[MicahGale]

Describe the bug

While playing around with a huge set of MCNP input files I found this error. I suspect it is due to the fact that the ParserBase distinguishes between 0 and non-0 numbers. I think this comes from this line.

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:

problem = montepy.read_input("foo.imcnp")
