update icite -k

[scbarrera]

Hello,
Thank you for creating such a lovely literature search tool!

When using icite -k or icite --print_keys the result is:

 YEAR/citations/references section:
     ----------------------------------
      YEAR: The year the article was published
         x: Total of all unique articles that have cited the paper, including clinical articles
         y: Number of unique clinical articles that have cited the paper
         z: Number of references

But the header while using icite -H is as follows:
YEAR cit cli ref

I would like to kindly request the following changes in the --print_keys display:

YEAR/citations/references section:
    ----------------------------------
     YEAR: The year the article was published
        cit: Total of all unique articles that have cited the paper, including clinical articles
        cli: Number of unique clinical articles that have cited the paper
        ref: Number of references

Thank you for your time.
