Hi team RTLCA

I have noticed that RTLCA re-calculates the total CO2-emissions _every time_ a material is mapped. So the software has two steps at the moment

1. Assign the mapped material to the `type`
2. Re-calculated GWPtot

This process takes a while. And if you try to map a new material while RTLCA refreshes, it tends to crash 😅

The question is, do we need to update the GWPtot calculation every time something is mapped? My suggestion is to remove step (2) and introduce a `Refresh calculation` button instead. This will save us a lot of hang time and will help us avoid errors 👍
