Add lzwCompress.js and lz-string to the benchmarks

It would be nice to be able to compare your library to those: https://github.com/floydpink/lzwCompress.js https://github.com/pieroxy/lz-string

Would it be possible to add them to the benchmarks ? Thanks

Good suggestion, you can add tests (benchmark) for these library following the tests in https://github.com/beenotung/compress-json/blob/05665812cb98aba0a0044bdea16495f4e3d765c7/test/compress-test.ts#L88-L113

lz-string seems to be binary compression, may not be fair comparison (because the underline storage engine may need to escape binary string before storing them which can add the storage size significantly);

I do not have access to the original sample data at the moment. Just did a trial with lzwcompress on another 50k sample data from the same online forum dataset.

Number of sample object: 50,000

-	JSON	compressed-json	compress-json	lzwcompress
Compressed Size	45M	36M	34M	42M
Compress Time	197ms	1.6s	2.6s	6.3s
Decompress Time	274ms	569ms	1.6s	560ms
Exact Match*	Yes	No	Yes	No

Remark: exact match consider whevether the order of object key is preserved when decompressed from the compressed representation.

In fact, the one I was the most interested in is lz-string. I'll look into it, thank you very much!
