fix: Fixes possible wrong lost events count

[Darkheir]

When the last sequence is equal or higher to the current sequence the uint to int conversion results in a wrong count.

Here's a simple example reproducing the issue:

last_sequence := uint32(10)
sequence := uint32(10)

int(sequence - last_sequence - 1)  // Will give 4294967295
