Proposed change: max carbs absorption limit in preferences

AndroidAPS 3.3-dev: Lates dev builds
Flavor: fullrelease

Observation:

I have been struggling with AAPS's carbs absorption for a long time. For me, carbs decay much faster than AAPS expects. In generally, this suggests IC/ISF profile settings may not be optimal.

No matter what I try:

• Either I have correct IC/ISF values, but carbs absorption in AAPS takes too long.
• Or carbs absorption in AAPS is ok, but IC or ISF values are not correct.

In both cases I end up with too much insulin and/or hypo's far too often.
In general, I solve this by either underestimating carbs intake or using latest option to enter negative carbs.

Tried with higher carbs absorption settings in preferences. Maximum value for min_5m_carbsimpact is currently limited to 12 mg/dL/5 min. A value of approximately 16 mg/dL/5 min proves to works much better for me.

Proposed change:
Proposing to change the max value in setting min_5m_carbsimpact from current max 12 to 24 mg/dl/5min.

Before doing a PR for this change, I would appreciate feedback on this proposal.

Start by locating the AndroidAPS preference definition for min_5m_carbsimpact and inspect how its maximum value is enforced. Confirm the preference accepts a maximum of 24 mg/dL/5 min, then run the relevant preference or Android tests if available and verify the setting can be selected in the fullrelease build.
