You can change the log level at any time by calling `setLevel()`.

To log to a custom location, pass a `Logger` instance to the constructor.
```java
HttpLoggingInterceptor logging = new HttpLoggingInterceptor(new Logger() {
  @Override public void log(String message) {

    parts.nextPart()!!
    val partMno = parts.nextPart()!!
    assertThat(partMno.body.readUtf8()).isEqualTo("mnop")

    assertThat(parts.nextPart()).isNull()
  }

  @Test fun `cannot read part after calling nextPart`() {
    val multipart =
      """
      |--simple boundary
      |
      |abcd
      |efgh
      |ijkl
      |--simple boundary
