To use this library, simply include Cutout.dll in your project or grab
it from NuGet, and add a reference to it.
<ItemGroup>
<PackageReference Include="Cutout" Version="x.x.x">
<PrivateAssets>all</PrivateAssets>
<IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
</PackageReference>
</ItemGroup>Then use the Cutout.Template attribute to define a template method.
The first parameter is the StringBuilder-like type to write to. Everything
else passed can be used in the template.
The template must be a compile-time constant string, so it can be defined
as a const field or inline in the attribute.
