Feature to add additional links to index files

[byungjikroh]

I have been using your Elixir sitemap library(https://github.com/ikeikeikeike/sitemap) and trying to use Go version this time.

But there is no add_to_index feature like Elixir version. It is a very important feature to me. Do you have an any plan to add the feature 'add_to_index' soon?

Thanks. :)

This is not possible without code changes

Each time you call Finalize() a sitemap will be added to sitemap index.

In my situation, I have some static site files to be merged into index file. Everytime I call Finalize(), it will only save the local sitemap (newly saved) to index file, not an existing one.
