Compatibility ods or xlsx files written using LibreOffice on Linux

[drorbemet]

First a thank you for this piece!
I like the approach of clj-excel-templates and would very much like to be able work with it on Linux.

Before can I say I've found an issue I would like to know if I overlooked something during my attempt to use clj-excel-templates with org.clojure/clojure "1.8.0" on files saved to disk using LibreOffice 5.0.6.2 00(Build:2) on Linux. I took the example xlsx-file and saved it back to disk with LibreOffice.
I am not even sure if that should be possible at some point, but I very much hope so :-)

Thanks for any hints.
