BrotliEncoderCompressStream with empty output causes BrotliEncoderTakeOutput to panic

[DoumanAsh]

It is a bit not clear whether encoder has own internal buffer like C library.
This panic happens when I feed empty next_out_array slice, and want to use BrotliEncoderTakeOutput result to write data without using own temporarely storage.

So just wanted to clarify if BrotliEncoderCompressStream can be used with empty next_out_array

P.s. it also seem to happen only when I push multiple chunks
