src/flac/decode.c : Fix a cast-align warning from GCC.

The old code was creating an array of FLAC__int8, and then casting
that to a set of signed and unsigned 16 and 32 bit integers. This
was replaced with a single union containing all the requred array.

This solution means that there are fewer pointer casts and actually
gives the compiler more information with which to generate fast code.
