Brotli support

[eweitz]

fflate is a remarkable library, and Brotli gives better compression than other techniques for common cases.

How feasible would it be to add Brotli support in fflate?

Not super feasible, unfortunately. Brotli is very similar to DEFLATE but it's so slow that it's impractical for real-time use. Moreover, beyond a certain level of complexity, WASM is faster than JS, and I expect Emscripten'd Brotli would be faster than fflate.

Brotli decompression is much more feasible because it is as fast as DEFLATE, but then again if you're looking for great compression ratios you may want to look into fzstd.

Thanks for the insight!
