name in string description of ARRAY8 type code is incorrect

When reporting a decode failure due to type mismatch, a stringified version of the unexpected type code is emitted for ease. The string reported for type code 0xe0 (representing ARRAY8) is described as "ARRAY32:0xe0" incorrectly instead of "ARRAY8:0xe0", i.e the string name is wrong but the type code itself is listed correctly.
