Target Framework dependency

[Vertigo093i]

Hello, @TimGeyssens.

First of all, thank you for the new v2 version.

Unfortunately it targets the .NET v4.8 which is higher than the original v4.7.2 supported by the Umbraco 8.x.
Would you be inline with them?

P.S. I'm getting the following error when trying to upgrade: The primary reference "C:\Users\<user>\nuget\packages\nibble.umbraco.uiomatic.addons.export\2.0.0\lib\UIOMaticAddons.Export.dll" could not be resolved because it was built against the ".NETFramework,Version=v4.8" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.7.2".
