Hits names should be quoted (like in the csv format)

[tetomonti]

The data table returned by hypeR includes in the hits column the names of the features (genes) separated by commas. To make it more robust, these names should be quoted, as is done in the '.csv' format.
I am using hypeR to perform enrichment analysis with metabolites (based on custom-made metabolite-sets), and often these metabolites have commas in their names. E.g., "5alpha-pregnan-3beta,20alpha-diol disulfate"
