Current implimentation of esp_http_ota does not perform any error-checking in the data writing phase calls `esp_ota_get_next_update_partition()` irrespetive of the received state of the image. A few additional error checking mechanism have now been added inside the esp_https_ota which returns the control in case an invalid header is received and a wrapper to the function `esp_http_client_is_complete_data_received()` of `esp_http_client` has been added.
Bugfixes:
- Fix http url redirection issue
- Fix basic/digest auth issue with http url
Features:
- Add support for adding custom http header
- Add support for reading firmware image header
- Add support for monitoring upgrade status
- This requires breaking down esp_https_ota API such that it allows finer application level control
- For simpler use-cases previous API is still supported
