Title: Relax enforcement of UTF-8 and use the body charset for decoding.

Consumers wanting well-behaved endponts should override or add to their `toBody` charset enforcement:

```java
String charset = Utils.parseCharset(body.mimeType());
if (!"UTF-8".equalsIgnoreCase(charset)) {
throw new ConversionException("Invalid charset " + charset + ". Must be UTF-8");
}
```

Closes #163.
