Summary

This PR enhances the test coverage for the StatsD parser by adding several new test cases and functions. The key changes include:

1. TestParseStatsdLine: Introduces a comprehensive set of test cases to validate the parsing of different StatsD metric types, including counters, gauges, sets, timings, histograms, and distributions. It also tests the handling of Datadog tags and various error scenarios.

2. TestParseKeyValue: Adds tests to ensure the correct parsing of key-value pairs, covering different edge cases such as missing keys or values and multiple equal signs.

3. TestParser: Implements tests for the parser function to verify its behavior with single and multiple metrics, handling of empty lines, and Datadog events.

4. Refactoring: Utilizes the assert package for more readable and concise test assertions.

These additions aim to improve the reliability and robustness of the StatsD parser by ensuring it correctly handles a wide range of input scenarios.
