experimental flag to transpile styled-components to next-yak

[jantimon]

Maybe we could add an experimental flag in the withYak config to automatically transpile styled-components code to next-yak. This feature would allow users to easily test existing styled-components-based projects with next-yak, potentially identifying performance improvements and compatibility issues.

Benefits:

1. Easier migration path for existing styled-components projects
2. Quick performance comparison between styled-components and next-yak
3. Identify areas where next-yak might need additional features to fully support styled-components syntax

Proposed Implementation:

• Add a new experimental flag in withYak config, e.g., library: "styled-components"
• When enabled, the loader would detect and transform styled-components imports to the next-yak equivalent

At the moment we don't support 100% of all features that styled-components has. Is the idea to somehow bail out if we find something that we don't support or just generate a warning?
