v0.53.0

# 💪 Added

## 🌀 Execution Engine `v1.6.0`

No more wrestling with `Batch[T]` vs. scalar inputs! The engine now auto-magically wraps scalars into batches when needed, so those annoying compilation errors are history.

* 🪄 **Auto Batch Casting**: scalars become batches on the fly.

* 📦 **Smarter outputs**: batches can expand or collapse consistently.

* 👉 Existing workflows **keep running just fine**. New workflows get all the power-ups. Only some new blocks will need to add additional manifest method to make use of new features

Please review our [change log 🥼](https://inference.roboflow.com/workflows/execution_engine_changelog/) which outlines all introduced changes.
