See https://jestjs.io/docs/ecmascript-modules for why --experimental-vm-modules
(VSCode doesn't like me putting comments in JSON!)
Maybe there's another solution involving fiddling with the tsconfig or transpiling but I didn't want to go down that road

Nice!
I've gone ahead and removed the images that were in the image-embedding-test bucket in the test-folder, because we don't need those anymore now that we can embed from localstack and test.

We are planning to implement resizing and TIFF-handling logic that will make all these tests pass.
First, we need to know exactly the requirements of Bedrock Cohere v3.
The AWS docs claim that the image can have a max size of 5 MB, but the tests prove that in actual fact that limit is 5 mebibytes (MiB), i.e. 5 * 1024 * 1024 = 5,242,880.
So PNGs and JPGs under the size limit currently work fine, but TIFFs of any size fail, as do PNGs and JPGs over the size limit.

This will hit Bedrock for real
