Add rows to list view for selected groups

[brianlove]

Add rows to the list view displaying the average data for each selected group (S&P 500, Fortune 500, etc). Groups currently have placeholder data, but this will be resolved in #123.

Styling to distinguish group rows from company rows will require changes to the UI Components <Table>, which is tracked in https://github.com/georgetown-cset/eto-ui-components/issues/341

Closes #101

👍 - one small thing, not sure this was introduced here but I noticed if I selected a company group and a company, the total displayed below the table by the pagination control is 1 larger than it should be

[brianlove]

For the "Viewing X of Y companies" at the top left, I'm displaying only the number of companies, not groups. The number in the pagination controls in the lower right is the total number of rows (companies + groups).

[jmelot]

@za158 do you have an opinion here? The only thing that occurred to me was changing the word "companies" to "results" in "viewing 502 of 1670 companies", and then including the sum of the number of companies and company groups in that text

[za158]

If feasible, I would prefer to put the word "rows" after 503 in that example image.

We will need to change the heading of the first column to something other than "Company" if groups are selected there, but we can figure that out later.

[brianlove]

Adding "rows" after "503" will require adding support for TablePagination's labelDisplayedRows prop to ETO <Table> (tracked in https://github.com/georgetown-cset/eto-ui-components/issues/362)

[brianlove]

@za158 Adding the pagination controls does add a mention of rows to that part of the table, but in a slightly different spot. Do you think this screenshot is sufficient, or do you still want it to say "1-10 of 503 rows"?

[za158]

This seems fine

[jmelot]

Two more small things:

1.) If you click on the name of the average row, you are directed to an empty company page - we should just not link to anything
2.) Can you add " (average)" after the name of the company group? It's not obvious that the figures in the row are averages, otherwise
