Upgrade to react-table v7

There appear to be some pagination bugs in react-table that aren't fixable without upgrading, but this is going to be an involved process due to how different the API is.

Specifically - if you have the privileges table, say "page 6 of 6" and then you apply a filter, the react table component may report "page 6 of 1" indicating that some elements of pagination don't update in the presence of filters.
