1.0.9: Fix Metrics Data Processing in MetricsBuffer

This pull request introduces optimizations to the way metric data is processed and managed in the MetricsBuffer class. These changes aim to improve the efficiency and clarity of the metrics batching process. Key updates include:

• Refactored Data Handling: Modified the loop that handles metric chunks to first convert the metrics set to an array outside the loop. This change avoids repetitive conversions within the loop, thereby enhancing performance.
• Batch Processing Optimization: Adjusted the slicing of metric data to be more directly associated with the newly created metric array, ensuring that slicing is handled cleanly and efficiently.
• Buffer Clearing Adjustment: Moved the buffer clearing operation outside of the namespace loop to ensure it only executes once all namespaces have been processed. This adjustment prevents premature clearing of the buffer, which could potentially lead to loss of metrics not yet sent.
• Enhanced Logging: Maintained and slightly adjusted the placement of debugging logs that output the content of each chunk, ensuring that this information is available for debugging without affecting the newly optimized flow of data handling.
