/// Dynamically update the compression level and compression strategy. The interpretation of level is as in <see cref="DeflateInit(int)"/>.
/// This can be used to switch between compression and straight copy of the input data, or to switch to a different kind of input data
/// requiring a different strategy. If the compression level is changed, the input available so far is compressed with the old level
/// (and may be flushed); the new level will take effect only at the next call of <see cref="deflate" />
/// </summary>
/// <param name="level">An integer value indicating the desired compression level.</param>
/// <param name="strategy">A <see cref="FlushStrategy">flush strategy</see> to use.</param>
/// <remarks>
/// Before the call of <see cref="deflateParams" />, the stream state must be set as for a call of <see cref="deflate" />, since the
/// currently available input may have to be compressed and flushed. In particular, <see cref="avail_out" /> must be non-zero.
/// </remarks>
/// <returns>
/// deflateParams returns <see cref="ZLibResultCode.Z_OK" /> if success, <see cref="ZLibResultCode.Z_STREAM_ERROR" /> if the source stream
/// state was inconsistent or if a parameter was invalid, <see cref="ZLibResultCode.Z_BUF_ERROR" /> if <see cref="avail_out" /> was zero.
