Metabase throws an OOMs on Excel export of complete data dump

[vinayvenu]

This issue happens because of the excel library used by Metabase does not use a streaming API while writing an Excel file. 

To get this working you will have to fix the issue on the docjure library

Fix issue on docjure (mjul/docjure#47)
Send PR to Docjure
Ask Docjure to do a release after incorporating the fix.
Update Docjure version used by Metabase and make necessary changes to use the Streaming API of docjure which you added.
Send PR to Metabase ((metabase/metabase#5187))
Once Metabase incorporates the changes and releases update the metabase version on reporting-openchs
