Eiger: Create a gantt chart of the arming process

To be able to optimise the arming of the Eiger, and to write the FastCS Eiger we need to understand the order of operations better. To do this we should make a diagram (something like a gantt chart) of what operations depend on others and how long they each take.

## Acceptance Criteria
* There is a diagram of what operations rely on what others in the eiger and how long they take
