A new expression for injecting values imported from/via Python like so ${__PY__:alviss.__version__}
This uses the ccptools.tpu.strimp.get_any(...) to import whatever the expression key points to and inject into the parsed config
The use case here is mainly to inject dynamic Python values into Alviss files "on-demand" like when using ccp-stencil templates in a CI/CD pipe so you can have the ever-changing version of the package you're working on injected automatically into the Alviss config file used as Context for rendering Docker files, Kube manifests and so on (similar to how it can be done in pyproject.toml)
This expression also adheres to the normal format of "defaults" (e.g. ${__PY__:alviss.__version__=Unknown}) and "required" (e.g. ${__PY__:alviss.__version__!=})
