Add Dana option to built-in pump simulator

[marionbarker]

This adds Dana as an option for the pump simulator for the Trio app.

Problem with this PR

This may be an existing Trio issue that is revealed by this PR.

I set Max Bolus and Max Basal to the allowed values for Dana (80U and 35 U/hr) and that was accepted when the in-app simulator was accepted.

Omnipod Accepted same limits

When I deleted the simulator and added Omnipod DASH, the Max Bolus/Basal values remained too big for Omnipod.

There should be some range checking when Omnipod is paired - the values are not saved to the pods because pods have no such concept, but the limits should be respected.

Medtronic works as expected

I then attempted to pair a Medtronic and got - max settings exceeded.
After changing the max values to 2 and 2 and pairing pump

• attempted maxBolus of 35 (this pump allows up to 25).
• No error message is presented to the user, but the value reverted to the original 2U that was there before.
• Seems like the error shown in the Xcode log should get picked up and reported:

2024-06-20 14:06:17.349292-0700 FreeAPS[14404:7137695] [MinimedPumpManager] Save delivery limit settings failed: command(MinimedKit.PumpOpsError.pumpError(Max setting exceeded))

• same comment for maxBasal - I attempted 35, which was accepted by this pump and then 70. The attempt at 70 was restored on the display to 35 (no error was reported - same message as above).

Tagging @avouspierre and @bastiaanv for review.

Status

Confirmed Omnipods have appropriate behavior
Change from draft to final, ready for approvals.

• Note - with this change the maxBolus and maxBasal can exceed Pod capabilities, but pumpManager limits requests to allowed values.
• It would be better to limit these values to the pump values but that is outside the scope of this PR

Details

I returned to test this with an Omnipod rPi DASH pod.
Set pump limits to DanaKit max:

• maxBasal = 35 U/hr
• maxBolus = 80 U

Attempt to set Omnipod basal rate to 35 U/hr.

• pump manager only goes up to 30 U/hr

Attempt to bolus 35 U:

• It silently limited the bolus to 30 U.
• Silent because the maxBolus was set higher than pumpManager allows
