Pref: export eventWithTime

[BelenLuo-tech]

When using emit, you do not know the type of event and can only write it as any[], which is not very elegant. rrweb should provide the type directly

This is for consumption by another typescript programme?
Is this something that we could add to https://github.com/rrweb-io/rrweb/blob/master/docs/recipes/ or is it trivial?

这是供另一个打字稿程序使用的吗？ 这是我们可以添加到https://github.com/rrweb-io/rrweb/blob/master/docs/recipes/的东西还是微不足道的？

Just provide an accessible type that can be recorded without going to https://github.com/rrweb-io/rrweb/blob/master/docs/recipes/
