[segmentio] Drop the event when message exceeds the maximum size

Hi 👋 . Is there any reason why the segmentio integration doesn't drop the event when the message exceeds the maximum size as the analytics-ios and analytics-android SDKs do? Looking through the files it seems like this was actually considered a year ago.

analytics.js-integrations/integrations/segmentio/lib/index.js

Lines 377 to 378 in a33206a

    
           // Print a log statement when messages exceed the maximum size. In the future, 
        
           // we may consider dropping this event on the client entirely.

I'm willing to open a PR if that is still considered.

I have opened a PR to change this: #599

	// Print a log statement when messages exceed the maximum size. In the future,
	// we may consider dropping this event on the client entirely.
