4.0.0 Release

This PR will serve as the list of items to complete and it will be updated to show the progress before finally merged into master when completed. We all have busy schedules, so if you want to help move this work forward then that is much appreciated!

The main theme is to reduce binary size

In two years it has grown from 280 kB to 1.4 MB and a lot of it is due to unnecessary syntactic sugar with many method overloads for various number types and nullable types - for every of our 800+ units! It simply adds up to a big total.

These items are chosen from #180, trying to include as many of the low hanging fruits as possible, while still keeping the list short and realistic to complete in a reasonably short time - we are all busy in our daily lives. We can always have more major version bumps later than trying to perfect it all now.

Feature complete before November, merged before mid-December

I would like to aim for a "beta" pre-release nuget sometime in October with all the items completed, so we can have some time to test it before releasing the final, stable 4.0.0 version before Christmas holidays.
We should have the work items list more or less final before Monday, October 8th.
