* \brief Initializes raw encoder

* This function may be useful when implementing custom file formats.
*
* \param strm Pointer to properly prepared lzma_stream
* \param options Array of lzma_options_filter structures.
* The end of the array must be marked with
* .id = LZMA_VLI_VALUE_UNKNOWN. The minimum
* number of filters is zero; the maximum is
* determined by available memory.
* \param uncompressed_size
* Size of the uncompressed data. If it is unknown,
* use LZMA_VLI_VALUE_UNKNOWN. You need to give the
* same value to the raw decoder to decode the data.
* \param allow_implicit
* If true, an implicit Copy or Subblock filter should be
* automatically added when needed. If this is false and
* an implicit filter would be needed, LZMA_PROG_ERROR is
* returned.
*
* The `action' with lzma_code() can be LZMA_RUN, LZMA_SYNC_FLUSH (if the
* filter chain support it), or LZMA_FINISH.
*
* \return - LZMA_OK
* - LZMA_MEM_ERROR
* - LZMA_HEADER_ERROR
* - LZMA_PROG_ERROR
