This update upgrades the go-parsesyslog dependency version to v0.2.2. It also enhances the server's connection handling. This is done by expanding the `HandleConnection` method to handle network errors and EOF scenarios more thoroughly, adjusting processing time measurements, and handling deadlines for connection processing. Furthermore, the initialization of the syslog parser has now been moved to the `NewServer` function for efficiency.
