This fixes a TODO item and unifies both decoders structures
It also fixes undefined behavior due to aliasing violations

I choose 2 fields instead of a union because mistakely using the
wrong type with a union will lead to hard to debug "wrong output"
while with 2 fields mistakely using the wrong type will crash
with a null pointer derefernce which is much easier to debug

2 of the changes are replaced by assert0s, as they should
be impossible.
The actual bug is likely caused by a invalid block_align
which is checked for and thus impossible in ffmpeg.

This is necessary since the switch to floating point
input means there is no longer sufficient input data
validation.
There is a good chance that other encoders are affected
by similar issues.
This problem can be triggered by trying to encode
extremely large values and probably also with Inf and
possibly also NaNs.

Odd chunk size makes no sense for stereo and incomplete chunks are

Simplify a little, assume empty frames are acceptable and
do not pointlessly reinit the bytestream2 contexts using
possibly wrong size values.
