SLY Syntax Error for Numbers in 'READ' cards

MCNP allows numbers 0123456789 in READ cards, but this causes a syntax error when parsing in MontePy.

MWE

testRead.imcnp:

Testing read card
C this is a comment
read file=file2read.imcnp

1 so 0.5 

mode n

There was an error parsing "read".

Hmmm. I suspect the read might not be the issue here.
