[Add] Implicit usings removed if enabled #58

[KreativJos]

Issues:

• The list of known implicit usings is simply coded to a default - https://dotnetcoretutorials.com/2021/08/31/implicit-using-statements-in-net-6/
  • [x] Should include items for different sdk types
  • Should take note of:
    • [x] <Using Remove="" />
    • [x] <Using Include="" />
  • [x] Should be configurable
• [ ] Should possibly check for other global usings?

Should possibly check for other global usings?

if it makes the extension smarter, the answer would be yes. OTOH if it increases the code complexity I'd wait a moment.

Questions:

• where should this global using file be located?
• should be configurable on workspace level?

I'd prefer to keep it out at the moment and open a new RF for it, at least until the thing gets clearer.
