Looking at the code, this is already the implementation - SupportedMediaTypes.json is built as an embedded resource into the .dll, which can optionally be overridden by placing a file version in the assembly path.

InterFAX.Api.csproj

<ItemGroup>
  <EmbeddedResource Include="SupportedMediaTypes.json" />
</ItemGroup>

Documents.cs

private Dictionary<string, string> _supportedMediaTypes;
public Dictionary<string, string> SupportedMediaTypes
{
    get
    {
        if (_supportedMediaTypes == null)
        {
            var assembly = Assembly.GetAssembly(typeof(Documents));
            var assemblyPath = Path.GetDirectoryName(assembly.Location);
            var typesFile = Path.Combine(assemblyPath, "SupportedMediaTypes.json");

            if (!File.Exists(typesFile))
            {
                // unpack the types file to the assembly path
                using (var resource = assembly.GetManifestResourceStream("InterFAX.Api.SupportedMediaTypes.json"))
                {
                    using (var file = new FileStream(typesFile, FileMode.Create, FileAccess.Write))
                    {
                        resource.CopyTo(file);
                    }
                }
            }

            var mappings = JsonConvert.DeserializeObject<List<MediaTypeMapping>>(File.ReadAllText(typesFile));
            _supportedMediaTypes = mappings.ToDictionary(
                        mapping => mapping.FileType,
                        mapping => mapping.MediaType);
        }
        return _supportedMediaTypes;
    }
}
