  avcodec/magicyuvenc: Switch to unchecked bytestream2 API
  
  We have already calculated the size of the packet
  and therefore don't need to rely on these implicit checks.

  avcodec/magicyuvenc: Calculate proper packet size in advance
  
  This can be easily done because we have a count of the number of
  values and the length of the associated codes. This allows
  to switch to ff_get_encode_buffer() and thereby avoids an implicit
  intermediate buffer.

  Do it before writing the actual slice to be able to use
  a single AV_WN32().

  avcodec/magicyuvenc: Avoid intermediate buffer
  
  Given that we can calculate the size of each slice in advance,
  we can determine the position in the output packet where it
  needs to be put and can therefore avoid the intermediate buffer.
