Convert a New Base 60-encoded number into an Integer.

Valid New Base 60 characters are alphanumeric or underscores (that is, they individually match the regex `[a-zA-Z0-9_]`). Invalid characters will be treated as if they did not exist. Empty strings will evaluate to 0.

If the resulting value is larger than 2sup128/sup, then this function will return None.
