improve packed encoding test vector

Browse Source 
packed byte length of ints now unambiguously shown to be type-dependent, not value dependent e.g. uint16(0x03) is 0x0003 not 0x03

@ -611,15 +611,15 @@ Through ``abi.encodePacked()``, Solidity supports a non-standard packed mode whe
This packed mode is mainly used for indexed event parameters.
As an example, the encoding of ``int8(-1), bytes1(0x42), uint16(0x2424), string("Hello, world!")`` results in:
As an example, the encoding of ``int16(-1), bytes1(0x42), uint16(0x03), string("Hello, world!")`` results in:

More specifically:
- Each value type takes as many bytes as its range has.
