Implement buffering & flushing of logs

Rough overview how it should work:

Buffer: Can hold a maximum of 100 logs at once

• A queue might be preferrable here

Flush Triggers:

• Idle Timeout: After capturing a log, a 5-second idle timeout is set. If no new logs are captured during this period, the buffer is flushed.
  • Each new log resets the idle timeout
• Visibility Change: When the app becomes hidden / goes into background logs are immediately flushed to ensure data isn't lost.
• Buffer Size Limit Reached: when buffer exceeds 100 logs, it's automatically flushed.
  • If you add 101 logs, the SDK will flush at the 100th, the other logs will after flushing then be added to an empty buffer (data isn't lost)
