VsCode extension for generating adapters

**Describe alternatives you've considered**
Currently we have only 2 ways: to write adapter manually or to use codegeneration.
Manual creation is boring and error-prone. While codegeneration is very slow, and I try to avoid it as much as possible.
But VsCode extensions generate code instantly

**Describe the solution you'd like**
Consider creating an IDE extension.

So on Ctrl+. on class name I invoke the menu, where should be entry "Generate Hive TypeAdapter". On click, it will analyse the current model class and create a TypeAdapter boilerplate

No files, tests, or extension entry points are identified. Start by reviewing how adapter code generation currently analyzes model classes, then determine the VS Code extension scope and integration point; done means a Ctrl+. action can generate the requested Hive TypeAdapter boilerplate from the current model class.
