zlib seems to produce better results than bzip2:

On my computer:
original size: 1440
Using bzip
compressed size: 541
Time to compress: 1.298 ms
Time to decompress: 0.527 ms
original size: 1440
Using zlib
compressed size: 413
Time to compress: 0.449 ms
Time to decompress: 0.163 ms

Current patch is simple, it always compresses IBF using zlib (default settings via Boost) before appending to name:
https://gerrit.named-data.net/c/PSync/+/4906
Should options be given to the application to:
- To not compress?
- For using other compressions (bzip2 and gzip)?
- To configure compression options (ex: fastest time vs smallest size)
If yes to any of the above, should I work on them in this change or defer to future change (post-release)?

Compressing is unimportant. Instead, move IBF into Interest.Parameters or Data.Content.
