Static initialization order fiasco in error.cpp curl_error_map

[MarkRakhmatov]

Description

I use boost/ut framework for unit testing, I create test suites as static objects (recommended by framework authors):

suite<"client"> clientTest= []{
    "login"_test = [] {
        cpr::Response getResp = cpr::Get(cpr::Url{"..."});
        ....
    };
}

It result in runtime error:

It looks like static initialization order fiasco

P.S. thanks for your work, it is awsome

Example/How to Reproduce

1. Create a cpr::Response getResp = cpr::Get(cpr::Url{"..."}); with static storage duration

#include <cpr/cpr.h>

cpr::Response getResp = cpr::Get(cpr::Url{"https://example-website.com"});

2. See error

Possible Fix

Please, consider replacing static unordered_map with function like this:

ErrorCode curl_error_to_error_code(std::int32_t curl_error) {
    switch (curl_error) {
        case CURLE_OK:
            return ErrorCode::OK;
        // and so on ...
        default:
            return ErrorCode::TOO_LARGE;
            
    }
}

Where did you get it from?
