chore(deps): add packages

This adds the following packages:
 - react virtualized
   This is the library we are using for our virtual list it is providing
   us with the multiGrid component which we use for our table.
 - memoize one
   This is a function which will cache return values based on the
   parameters, so it will only execute if the parameters change
 - enzyme-to-json
   This will generate a json for snapshot testing from enzyme objects.
   Unfortunately testing the table is cumbersome with the react
   renderer.
 - jest-emotion
   This will provide the possibility to render the css created by
   emotion instead of just the css class names. By that we can also test
   the resulting css. Which is important for the table.
These packages are needed for the
Table component.
