Can we switch to .Net ver 6.0?

[samlegus]

The assembly targets .Net ver 3.5 by default, there are features in 6.0 that me and one of my students would really love to use in SuperEditor - we've tried a lot of things but can't find a way to change the target since everything is in a .dll

this might fix some of the bug with linux too.
right now the plugin is completely broken and unusable on linux.
