v0.3.3

What's Changed

• Harden EIP-712 encoding of non-integer types so malformed input throws instead of being silently misencoded. The address encoder now validates a 0x-prefixed hex string of at most 20 bytes; bytes/bytesN values with odd-length or non-hex input, or wider than 32 bytes, are rejected; and the shared hex parser rejects odd-length and non-hex strings rather than truncating. (#532)
• Validate integer values before EIP-712 encoding instead of silently wrapping out-of-domain values. A negative value for an unsigned uint* type now throws (previously it wrapped into a huge positive integer via two's complement); values exceeding the declared width are also rejected. In-range signed int* two's-complement encoding is retained per EIP-712. (#530)
