Apache 2.0 Conversion

Each version of AiDotNet automatically converts to the Apache License 2.0 four years after its initial release. This means that every version eventually becomes fully open-source with no restrictions. The BSL license ensures the project is sustainable while guaranteeing eventual open-source availability.
