conversion of rT.variables in mg/dL

[mountrcg]

Needs to be done in parallel with nightscout/trio-oref#30

This concerns mainly ISF as transmitted from oref to suggestion / enacted. So far I only found one instance where ISF is used.

So far ISF is always transfered from oref in the current user glucose unit, so if mmol/L is used it comes in mmol/L. Therefore currently no conversion is applied in Trio to ISF originating from oref. Drawback is also that a change of user glucose unit will not be reflected in ISF unless a new loop is calculated. Refer also to nightscout/trio-oref#29

Also the watch app needs to adjusted as ISF may also be shown on watch.

I need a little help on the watch part, still throws an error in the conversion function

Trio/FreeAPS/Sources/Services/WatchManager/WatchManager.swift

Line 211 in a731a13

from: (units == .mmolL ? isfValue.asMmolL : Decimal(isfValue)) as NSNumber

successfully tested!
As Trio does not show ISF anywhere on UI, only watch can be used to review the changes.
Old sitiuation - ISF is only shown converted after a new loop

original state ISF	after unit change, no new loop	after new loop

After change, ISF is immediatly converted after changing units on phone. As it can be seen the popup still shows units from last loop, watch already has ISF converted.

original state ISF	after unit change, no new loop
