.gz support for kreport script about centrifuge HOT 4 OPEN

@ffinfo, you can pipe into centrifuge-kreport. That means one of the two following ways should work, depending on your shell:

gunzip -c centrifuge-out.gz | centrifuge-kreport -x IDX 
# or, using an in-place file (with bash)
centrifuge-kreport -x IDX <(gunzip -c centrifuge-out.gz)

Can you try that?

Oh good, going to try this. Well let you know if this works.
Maybe good to add this to the usage of the script/tool?

from centrifuge.

The first one does not work because centrifuge-kreport does not read from stdin.
The second one is basicly a inline fifo pipe, this does work.

For usability it's might be a good thing to let the tool also accept input from stdin and directly from a .gz file.

Fixed the input from STDIN. Will add the feature to read directly from a gzipped file in the future.
