Please Test `Elixir` `cid` matches the output of `Go` and `Dart` version 🧪

We have an issue with the build failing for our imgup app because the cid (which is used as the filename) for the images uploaded to S3 has changed ... 😕 We need to:

• [ ] investigate & confirm that the cid created in Elixir is identical to the one created by Go
• [x] and correspondingly, identical to the one created by the Dart implementation of cid.

This is as easy as:

cd ~/code/cid
iex -S mix

iex(1)> Cid.cid("hello")
"bafkreibm6jg3ux5qumhcn2b3flc3tyu6dmlb4xa7u5bf44yegnrjhc4yeq"

It's probably this line change:

https://github.com/dwyl/cid/commit/7c3e41bc9750ffbc31ae6b64f3f50ccfa6af928c

imgup is failing because the CID that is being created is becoming base58BTC instead of the previous base32

[nelsonic]

Indeed. base58 is preferable to base32 because it uses fewer characters to represent the same cid. 💭

[nelsonic]

Lowering the priority of this in light of the fact that https://github.com/dwyl/imgup/pull/122 is merged and on main of imgup ✅

We still want to confirm that cid created in Dart matches the one in Elixir. That is probably a T5m task if you have the project open on your Mac ...

[LuchoTurtle]

Running a locally created test on dart_cid yields a correct response:

      String input = 'hello';
      final output = CID.createCid(input, Multibase.base32).cid;

      expect(output == "bafkreibm6jg3ux5qumhcn2b3flc3tyu6dmlb4xa7u5bf44yegnrjhc4yeq", true);

00:01 +28: All tests passed!

Cool. As long as they match we're all good. 👌 🙇

@nelsonic can't find the repo for the Go project. Where is it?
