Is your feature request related to a problem? Please describe it

Currently when using dynamic config in a mono-repo, and let's say you have subfolders that shoud be incharge of their own CI - using this package provides great flexibility - because each subfolder can create it's fine grained requirements for their CI

The issue is that sometimes the subfolder would prefer a simple - none dynamic yaml instead of creating it from code

The problem is that circleci has tools (circleci config pack) to either work only with config.yml or only with the sdk

If the SDK could import a partial config.yml file then we could orchestrate using both sdk usage and specific config.yml

Describe the solution you'd like

Be able to import a config.yml file into an sdk represented object

What is the motivation / use case for changing the behavior?
