Mailmark Barcode type class Royal Mail Mailmark 4-state barcode, types C and L

The Application String is split into six fields, each field is converted to an integer, the integers are consolidated into a single value, the value is split into data numbers of thirty or thirty two values, Reed Solomon check numbers over GF(32) are appended, every number becomes a six bit symbol of a fixed parity, the symbols are reordered into extender groups and each group drives the ascenders and descenders of three bars.

The type of the barcode follows from the length of the Application String: twenty two characters for the type C, twenty six for the type L.
