Add options to brotli and implement clean brotli .br support

Browse Source 
- allow to specify brotli window size
  - parameter -m0=brotli:long=n, BROTLI_MAX_WINDOW_BITS (24) used by default in brotli-mt, smaller == faster
  - note that :long can be set up to BROTLI_LARGE_MAX_WINDOW_BITS (30), whereas :wlog can be set up to BROTLI_MAX_WINDOW_BITS (24) only...
  - todo: check whether set of BROTLI_PARAM_LARGE_WINDOW to BROTLI_TRUE is needed if (lgwin > BROTLI_MAX_WINDOW_BITS)

- implementation of single-threaded brotli compression / decompression for .br data
