Please extend the response of models().getList() request by metadata and permissions

[TheTDD]

Working with T-Systems OpenAI interface, I have found that it delivering also metadata on models().getList() request, which are missing in Simple-Openai API.

Here is the example of one model Info:

OpenAiListModelsResponse(object=list, data=[OpenAiListModelsResponse.ModelInfo(id=Llama-3.3-70B-Instruct, object=model, created=Wed Jan 21 10:01:19 CET 1970, ownedBy=T-Systems International, metaData=OpenAiListModelsResponse.Metadata(modelType=LLM, sourceType=OPEN SOURCE, maxSequenceLength=128000, hiddenSize=0, maxOutputLength=0, deploymentRegion=otc-germany, location=otc-germany, license=https://www.llama.com/llama3_3/license/, displayName=Meta LLama 3.3 70B, deploymentCountry=Germany, EU, inputModalities=[text], outputModalities=[text], isExternallyHosted=false, endOfLifeDate=null), root=Llama-3.3-70B-Instruct, parent=null, permission=[OpenAiListModelsResponse.Permission(id=modelperm-b6492ab95c7e4ffab5d152ea72c144c9, object=model_permission, created=Wed Jan 21 10:01:19 CET 1970, allowCreateEngine=false, allowSampling=true, allowLogprobs=true, allowSearchIndices=false, allowView=true, allowFineTuning=false, organization=T-Systems International, group=null, isBlocking=false)]), ..

Both metadata and permissions are missing in io.github.sashirestela.openai.domain.model.Model class.

Please add those, as the metadata is very important for my project, and actually I have to send a raw request and parse the data outside of simple-openai.

Here are my metadata and permissions classes;
