Inverse Bloom Filter: wrong result after ReadFrom gzipped i/o stream

[shenwei356]

Hi, Thanks for writing this useful package, I like it very much.

However when I found a problem as the title said when using InverseBloomFilter.

I edited the test code (attached below) for writing and reading a gzipped i/o stream for saving disk space, but the result said

Expected both filters to Test the same for 0

And when switching off gzipped, i.e., no compression, everything is OK.

I also test the ScalableBloomFilter, these's no such problem.

Please help, thanks for your time.

Reading compressed file using bufio.NewReader(r) and without gzip.NewReader causes error too.
