Pull Request Details 📖

Description

Both the esp_wifi_remote and esp_hosted bindings have been added, along with a fix for a missing ESP_IDF_VERSION set that comes from the get_idf_version function in idf_tools.py, which is called by idf.py during build. Since we're not using idf.py directly, we're missing this environment variable and setting it here fixes this gap for modules that use it.

Testing

With some changes to esp-idf-svc, was able to successfully connect to a 2.4 GHz wifi network using a test app:
