Add timer component to RED

[thomas-gleiforst]

The timer is the last major component from WPF basestation that hasn't made it into Electron basestation. The features and functionality are pretty well defined in that this component is expected to have an editable, save-able task list (likely in the form of a json) where a named major task with a time limit and several other named smaller subtasks are loaded, added to a queue, and the user can start a timer, progress through the tasks, and track their delta between their current performance, their desired performance in this leg, and their desired performance overall.
During a rigorous design phase in 2019-2020 it was decided that for clarity their should be a count-up timer on the left and a count-down timer on the right so that drivers at basestation always have the information they need readily available.
