Module esp32_hal::prelude

The prelude.

To use the esp32_hal effectively, a lot of traits and types need to be imported. Instead of importing them one by one manually, the prelude contains the most commonly used imports that are used around application runtime management.

This can be imported as use esp32_hal::prelude::*.
