* Run dotnet format style after rebase

* Run dotnet format analyzers after rebase

* Run dotnet format after rebase and remove unused usings

- analyzers
- style
- whitespace

* Add comments to disabled warnings

* Remove a few unused parameters

* Replace MmeShadowScratch with Array256<uint>

* Simplify properties and array initialization, Use const when possible, Remove trailing commas
