This adds an additional display output for the progress indicator to
support a json output. It refators the progressui package a bit to add a
new method that takes in a `SolveStatusDisplay`. This
`SolveStatusDisplay` can be created by the user using `NewDisplay` with
the various modes as input parameters.
The json output will print the raw events as JSON blobs. It will not
throttle the messages or limit the display. It is meant as a pure raw
marshaling of the underlying event stream.

No other parts of the progress rendering modify the inputs, so we should
avoid this as well.
This actually fixes an edge case in pushWithMoby which writes the same
VertexStatus multiple times, modifying the timestamps and similar.
However, if the operation takes long enough the small time difference
can accumulate, and move the Start time far into the past.
