+Fields

+Fields which are read from isis are in format 999x where 999 is three
+digit ISIS field and x is isis subfield. There are three special ISIS
+fields supported: 10 and 11 (used for ISBN and ISSN, those are only
+fields which have just two digits) and MFN which returns ISIS MFN.

+It's done using simple algorithm: it first selects prefix and then
+inserts fields (and their separators) or just skips them (so it groups
+fields and separator right from it). At end it just appends suffix.
