Full Changelog: v6.6.2...v7.0.0

v6.6.2 (bug fix)

fix json-parsed inputs & outputs had name field set;
optimize static byte array type initialization (bytes<M> and function);
add SuperSerial methods: toRLP and fromRLP;

SHA-256 (headlong-6.6.2.jar): 3ea4efb6132bd22396f72dd13af350bcfa7f0ba36bc749b5cc11f01738775634

v6.6.1 (bug fix)

fix IntType and LongType encode and validate would accept any subclass of Number if its longValue() was in range -- could occur when compile-time type-checking was bypassed (by casting to ABIType<Object> or using TypeFactory.createNonCapturing or TupleType#getNonCapturing);
consistent exceptions among UnitTypes for class mismatch -- always IllegalArgumentException and not ClassCastException;
improve illegal boolean error message in SuperSerial;
