Custom BannedSymbols file name and extension

I am trying to use the Microsoft.CodeAnalysis.BannedApiAnalyzers package in Unity.

The problem I have is that Unity requires that the name has to have a specific format and the extension is `.additionalfile` so it will not work correctly because it will not be able to call `BannedSymbols.txt`.

https://docs.unity3d.com/Manual/roslyn-analyzers-additional-files.html

That is why I would like to configure the format of the name and extension to be discovered by this package so that it can work with Unity and incidentally to be more customizable and not have the restriction that the name and extension has to be a specific one.
