Add a debouncer

[bitsandfoxes]

It’s easy for the SDK to end up capturing a ton of errors in a short amount of time. For example, if there's a script error in _process, the SDK can capture every single one. This could quickly burn through a user’s quota without providing much helpful info.

Why this is a problem

• You can blow through your quota super fast i.e. with errors in _process or _physics_process
• Sending a bunch of errors in one go could impact performance, especially during gameplay.
• A bunch of duplicate errors are not going to be terribly useful anyway

How this could help

Adding a debounce feature would make error reporting smarter by:

• Limiting frequency: Only capturing one error every X seconds, for example. We have a very naive implementation like this in the Unity SDK
• Skipping duplicates: If the same error happens repeatedly (like in a loop), don’t capture it every time. But how would we detect duplicates?

how would we detect duplicates?

Maybe keeping a count keyed by (file, lineno)
