Serve static files

You can serve static files with some limitations:

• you can’t serve on the root path
• all static files must be under /src/main/resources/assets folder
• path and folder must have the same structure

For example, you can serve the file /src/main/resources/assets/foo/style.css with the url http://localhost:4545/foo/style.css.

import topinambur.http

@Test
fun `serve static files`() {
    HttpServer()
        .assets("/foo/*")
        .start().use {
            assertThat("http://localhost:4545/foo/style.css".http.get().statusCode).isEqualTo(OK_200)
        }
}
