go-zero: How to set timeout params in sqlx.NewMysql

Hi,

I want to set some mysql params (e.g. timeout), but I found the SqlOption is private var.

func NewMysql(datasource string, opts ...SqlOption) SqlConn {
	opts = append(opts, withMysqlAcceptable())
	return NewSqlConn(mysqlDriverName, datasource, opts...)
}

SqlOption func(*commonSqlConn)

So how to fix or workaround?
