linelayer支持在线上面显示label吗？

* **L7 Version**:
* **Platform**:
* **Mini Showcase(like screenshots)**:
* **CodePen Link**:

想要在线上显示一个标题，看文档没有找到相关配置，是不是不支持这个功能？有个思路是在线上去一个点来把这个标题通过其他图层画出来，但是这样的标题是水平的，不能跟线同一个方向。

The request concerns labels displayed along a line layer, but it names no source file, test, version, platform, or reproducible example. Start by checking the line-layer documentation and implementation to determine whether line-following labels are supported; done should mean a label can be rendered on a line and follow its direction.
