Does go-mysql support HEARTBEAT_LOG_EVENT_V2?

[JasonMing]

Since MySQL 8.0.28, a new binlog type HEARTBEAT_LOG_EVENT_V2(41) was added for support >4GB single file.(https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-28.html#mysqld-8-0-28-bug)

However, the replication.EventHeader.LogPos is still a uint32 until the report time(v1.13.0).

@JasonMing I think the fix for this is probably straight forward. Do you want to try to create a PR for this?
