NodeJs script to w3s delegated upload

[red-0ne]

NodeJs script that uploads a file to w3.storage given a delegation proof. It takes the following arguments

--path Path to the file to upload.
--secret ed25519 base64 encoded private key.
--delegation base64 encoded proof coming from client.

It outputs CID of the uploaded file to stdout.

Note: It uses some ES modules that prevented packaging by pkg.

From cmd/, install direct dependencies:

npm i @ipld/car @noble/ed25519 @ucanto/principal @web3-storage/access @web3-storage/w3up-client command-line-args

Test

We create the user and setup a delegation proof that will be used by our script.

$ npm i -g @web3-storage/cli

$ w3 whoami

$ w3 space create test

$ w3 space register email@address #should receive an activation link, this resolved after requesting the link

$ w3 delegation create did:key:z6MkkwKy2C9sCgoWcCGgxVCCt1qFyLJzwkoWi9BF3zi5s5jw | base64 -w 0 # LivePeer's DID key

Closes livepeer/catalyst#365

Thanks for the PR @red-0ne .

I skimmed through and it looks nice. I think it'll be the way to go to use this script instead of the w3 CLI binary, mainly because of multi-tenancy and the fact that we're better off keeping credentials in memory.

Saying that, let's park it (and keep as draft) until I complete the work on the w3s driver (livepeer/catalyst#375). It should take no more than a few days. After that, we'll come back to your PR and fill the script with all the commands we need, plus do a the actual code review.
