should we compress data?

https://github.com/cruppstahl/libvbyte to investigate.

problem is for once w/o sorted it works only partially well. then the prefixing dalmatiner does will kind of throw it off, so we need to know if a metric is a float or an int and can't mix data in it -.-

possible to combine that with delta compression to even out the large issue that compression when data works best while small and the tag there is problematc

basically: compressed[n] = compress(v[n] - v[n-1]) that way we can easiely add data (by keeping a last known) and stream it by dynamically uncompressing it
