fix: update geolocation fallback API and use static country code mapping

[ucodia]

Description

Fixes geolocation fallback API call

Issue 1

The fallback API will always fail when using the HTTPS endpoint

curl https://ip-api.com/json/
{"status":"fail","message":"SSL unavailable for this endpoint, order a key at https://members.ip-api.com/"}%

Using the HTTP endpoint is not great because this could expose the application location to eavesdropper and be vulnerable to man-in-the-middle.

Issue 2

If the fallback API call fails, it reports on the wrong URL on the exception: https://github.com/ucodia/codecarbon/blob/ebc8d1a3f5dcae9013dcbe6883d05e711ad6ce28/codecarbon/external/geography.py#L136

Non-issue 1

The current fallback relies on another API to map the 2 letters country code to a 3 letters code. This is static data that almost never changes, by switching to a static mapping provider we can make the fallback more resilient.

Fixes #1101

Motivation and Context

Certain IP ranges are not covered by the primary API and therefore a fallback is necessary otherwise CodeCarbon client will estimate on the wrong energy mix.
