Invalid Event Fails Without Logging or Callback

## Expected Behavior
If an event doesn't get tracked for any reason (in my case because of an invalid event property value), I would expect to be able to configure a way to get notified about it, either through logging or through the callback function.

## Current Behavior
I was using the Amplitude client to track an event and noticed that it wasn't showing up in the Amplitude dashboard. After looking into it, it seems to be caused by a Python `datetime` object being passed as an event property (formatting it as a string resulted in the event being tracked). However, at no point did the library log an error (like it does for an invalid API key). Configuring a callback function also did not help - the callback function gets called for successful events, but not this particular error case.

## Possible Solution
I'm not sure if the current behaviour is a bug or by design, but there should be some way for the developer to know about a call to `Amplitude.track` failing for whatever reason.

## Steps to Reproduce

1. Track an event with a a Python datetime object as an event property value
2. No event gets tracked and it fails silently
