Use uuid in Map Matching response

Soon the Map Matching API will start returning a uuid field for all successful map match requests.

Once this field is returned for all profiles we should start using it in MapboxJava and remove the placeholder here https://github.com/mapbox/mapbox-java/blob/aa126fcad9e7dba2f5b7f74c5a46291463d9b85e/services-matching/src/main/java/com/mapbox/api/matching/v5/MatchingResponseFactory.java#L73

In the meantime, while we transition to including the uuid in all responses, we could consider adding optional parsing of the uuid field that falls back gracefully to the placeholder string. This could be useful for responses like NoMatch or NoRoute that don't return a uuid either.

从 services-matching/src/main/java/com/mapbox/api/matching/v5/MatchingResponseFactory.java 中 issue 引用的占位符开始，检查 Map Matching 响应的解析方式。将成功响应与 NoMatch 和 NoRoute 响应进行比较，以确定 uuid 的预期处理方式。当 uuid 存在时响应使用 API uuid，并在其缺失时仍保持正常行为，即表示完成。
