Code contributed by @the-bay-kay in #95

Summary from there:
Charging sessions without an ISO15118-2 Departure Time now have a preview graph that showcases the charging behavior.

See Issue #92 for additional context, and #92 (comment) comment specifically for a demo of this functionality!

Will try to install manually, and then switch to conda so we don't have to compile

Can confirm that this works on my x86 machine. But apparently does not work on arm.
I don't have time to investigate aarm versus x86 now.
But I am also not convinced that we need/should generate the power curve in node-red.
Who cares about a power curve that is negotiated every 24 minutes? Not any user.

Instead, let's have the charts in node-red populated from the car simulator using MQTT,
So this serves more of a debug function than a confirmation function.

Make the EV-computed curve more meaningful
422ca9f 
- Do not throttle the SASchedule from the EV based on departure time, only
  transmit the composite pmax schedule. The EV will deareate based on
  departure time
- Show the values in the current power delivery request instead of the
  progress towards the eamount so that we can see the impact of curtailing the
  pmax
- Pass in the pmax to the power curve computation algo, although it is
  currently a NOP
