memory leaks

[assistar]

Hollo there!

I found memory leaks.

inline
std::string Session::easyEscape(const std::string& text) {
    char *encoded_output = curl_easy_escape(curl_, text.c_str(), static_cast<int>(text.length()));
    return std::string{encoded_output};
}

This code needs to free memory.
For example like below.

inline
std::string Session::easyEscape(const std::string& text) {
    char *encoded_output = curl_easy_escape(curl_, text.c_str(), static_cast<int>(text.length()));
    const auto string = std::string{ encoded_output };
    curl_free(encoded_output);
    return string;
}
