Performance of Logging Extension

[Brunni]

As there might be really, really many log messages, it might be important to tune the extension regarding performance.

e.g. Remove the new list here:

gelf-extensions-logging/src/Gelf.Extensions.Logging/GelfLogger.cs

Line 113 in 22ee531

var additionalFields = new List<KeyValuePair<string, object?>>();

Why use ToArray here and not ToList?

gelf-extensions-logging/src/Gelf.Extensions.Logging/GelfLogger.cs

Line 42 in 22ee531

AdditionalFields = GetAdditionalFields(logLevel, eventId, state, exception).ToArray()

Hi, I'm very much open to introducing performance improvements where they make sense. Any improvements would need to be quantified with benchmarks however. If that is something you are interested in working on, then please feel free to submit some PRs.
