fix(datamart): somereason it stopped working.. and added download types

there was a weird issue with the req.query that cause nothing to pull and make the excel files
lag..... now excel macros are using the csv pull from here and added in the xlsx to download to bc
why not makes it easier for later  and can have bbuttons for every thing in lst too :D
