Add a method to "ESP8266HTTPUpdate" to pass "HTTPClient" object manually

[BrotherV]

I would like to update ESP firmware from AWS and I need to add some specific headers to the "HTTPClient" object and pass it down to the "ESP8266HTTPUpdate" class to update the firmware.

Suggestions
Adding a method to the .h an .cpp file

ESP8266httpUpdate.h

t_httpUpdate_return update(HTTPClient &http, const String &currentVersion = "");

ESP8266httpUpdate.cpp

HTTPUpdateResult ESP8266HTTPUpdate::update(HTTPClient &http, const String &currentVersion)
{
    return handleUpdate(http, currentVersion, false);
}

How to use

    HTTPClient *httpClient = new HTTPClient;
    httpClient->begin(*client, url_WiFi);
    httpClient->addHeader(F("h1"), "XXXXXXX");
    httpClient->addHeader(F("h2"), "XXXXXXX2");
    httpClient->addHeader(F("h3"), "XXXXXXX3");

    ESP8266HTTPUpdate *otaUpdater = new ESP8266HTTPUpdate;
    t_httpUpdate_return ret = otaUpdater->update(*httpClient);
