Remove using isdigit since its deprecated

I had put an extra check to see if instance number is a digit
and used POSIX::isdigit for that. However, it's deprecated in
the PERL version that is in the mrw-tools.

Also, no other parsers are doing this explicit check since
the instance number has to be digit and is fundamental and
hence isdigit check is not needed.
