Hotfix for https://github.com/langchain4j/langchain4j/issues/23

Added "Dynamic Tools": Now, the LLM can generate code for tasks that require precise calculations, such as math and string manipulation. This will be dynamically executed in a style akin to GPT-4's code interpreter! We use Judge0, hosted by Rapid API, for code execution. You can subscribe and receive 50 free executions per day.

• Now you can add your custom knowledge base to "AI Services". Relevant information will be automatically retrieved and incorporated into the prompt. This way, the LLM will have a context of the data and will answer based on it!
• The current date and time can now be automatically injected into the prompt using special {{current_date}}, {{current_time}} and {{current_date_time}} placeholders.

Added support for Spring Boot 3

• Added Spring Boot Starter: https://github.com/langchain4j/langchain4j-examples/blob/main/spring-boot-example/src/test/java/dev/example/CustomerSupportApplicationTest.java
• Added support for HuggingFace (chat+language) models

Added support for tools (OpenAI functions): https://github.com/langchain4j/langchain4j-examples/blob/main/other-examples/src/main/java/ServiceWithToolsExample.java

• You can now define ChatMemory in AiServices and it will keep history of your interactions
• Added OpenAI moderation model, so you can moderate texts, documents and messages
• Added auto moderation for AiServices. Just put @Moderate on top of your method and it will automatically verify that user input does not violates content policy

HuggingFace embedding models are now supported via HF Inference API

• renamed from ai4j to langchain4j
• big design changes
• added "AI Services" (declarative AI facades)
• added more document loaders and splitters
• added in-memory embedding store
