Include Basic Stats (by Study) on the Site

[PaulHeggarty]

In an email on 14th June 2018, for the SAB I requested basic stats for both the SndComp and CoBL databases. So @Bibiko already has the SQLs for these, but the results should also appear somewhere on the sites themselves, on the Sound Comparisons about page (or a new 'Stats' page), and on the CoBL homepage. See also the corresponding issue for CoBL, at:
https://github.com/lingdb/CoBL/issues/467

Stats for Sound Comparisons

A table with 1 study per row, and then a totals column for all studies taken together, with these columns:

• The total number of languages/dialects/accents.
• The total number of word-by-word sound files.
• The total number of phonetic transcriptions.

Perhaps also ...

• The total number of translation entries.
