New auto-generated python api client released

For developers out there who use openapi to auto-generate documentation and client libraries. If you need to do this in python, please consider using the new https://github.com/OpenAPITools/openapi-generator/blob/maste... generator, which I wrote.

Some reasons to use it:

  - it preserves spec case in model properties and endpoints
  - it enforces run time type checking
  - it has more robust composition (oneOf/anyOf/allOf) than the python generator
  - it has type hints
  - api loading is quicker (one can load one endpoint vs all of them automatically loading previously)
  - one can check if an instance validated against a schema by checking if the instance is an instance of the schema class
  - it uses python >= 3.9
  - it includes type: string format: number Decimal support so now you can send numbers as strings and preserve precision
  - enums are now accessible as class constants
  - uniqueItems validations added
  - multiple content types supported in endpoint request bodies + responses
