Optional consumeWhether or not to "consume" the source data. This will make the typed array/buffer you pass in unusable but will increase performance and reduce memory usage.
Optional dictionaryThe dictionary used to compress the original data. If no dictionary was used during compression, this option has no effect.
Supplying the wrong dictionary during decompression usually yields corrupt output or causes an invalid distance error.
Optional sizeThe original size of the data. Currently, the asynchronous API disallows writing into a buffer you provide; the best you can do is provide the size in bytes and be given back a new typed array.
