OkHttp Brotli Implementation
============================

This module is an implementation of [Brotli][1] compression.
It enables Brotli support in addition to tranparent Gzip support,
provided Accept-Encoding is not set previously.  Modern web servers
must choose to return Brotli responses.  n.b. It is not used for
sending requests.

```java
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(BrotliInterceptor.INSTANCE)
  .build();

import okio.sink

internal fun Main.commonCreateRequest(): Request {
  val request = Request.Builder()

  val requestMethod = method ?: if (data != null) "POST" else "GET"

  val url = url ?: throw IOException("No url provided")

  request.url(url)

  data?.let {
    request.method(requestMethod, it.toRequestBody(mediaType()))
  }

  for (header in headers.orEmpty()) {
    val parts = header.split(':', limit = 2)

 *  **OkHttp now uses `@Nullable` to annotate all possibly-null values.** We've
    added a compile-time dependency on the JSR 305 annotations. This is a
    [provided][maven_provided] dependency and does not need to be included in
    your build configuration, `.jar` file, or `.apk`. We use
    `@ParametersAreNonnullByDefault` and all parameters and return types are
