MAINT: crackfortran regex simplify

* remove extraneous character class markers used in
`crackline_re_1`: `\w` and `=` on their own have no
benefit to character class `[]` inclusion

* `name_match` has a character class that can be
simplified because `\w` metacharacter already
encompasses the digit metacharacter and the
underscore
