Feature request to allow `props` to `propTypes` conversion when `assert` is `false`

This is a:

- Feature Request

Which concerns:

- babel-plugin-flow-runtime

---

### What is the current behaviour?

Currently the babel-plugin-flow-runtime does not convert `props` to `propTypes` when the babel plugin option `assert` is set to `false`.

---

### What is the expected behaviour?

Request to have another option or configuration to allow `props` to `propTypes` conversion when `assert` is set to `false`.

---

### Which package versions are you using?

flow-runtime v0.12.0

Start by tracing the babel-plugin-flow-runtime handling of the assert option and the props-to-propTypes conversion. Define how conversion should behave when assert is false, including whether a separate configuration is needed, then verify that the requested conversion works without enabling assertions.
