[parser] adding postcode context features and associated data structures to the parser. Masking digits, which should hopefully help with generalization. Creating positive/negative features for postcode with and without context support. Note: even with known postcodes in known contexts, only use the masked digits to avoid creating too many features that are redundant with the index.
