Implement validateExportStream function

[dmitrizagidulin]

Implement (and export from the npm library) a validateExportStream function.

• Takes a readable stream (of the tarball) as input
• Unpacks it (extract the code from importActorProfile function)
• Validates it
  • ensure it has a manifest.yaml file (later on we're gonna check the schema on that file too)
  • has an activitypub top level folder
  • the folder has the files activitypub/actor.json and outbox.json
  • the contents of those two JSON files can be parsed as valid JSON (so, JSON.parse() doesn't throw error)

See spec at https://codeberg.org/fediverse/fep/src/branch/main/fep/6fcd/fep-6fcd.md#activitypub-export-example

(Export endpoint defined in FEP https://codeberg.org/fediverse/fep/src/branch/main/fep/9091/fep-9091.md, implemented in Hollo already by @0marSalah )

import { validateExport } from '@interop/wallet-export-ts'

const exportEndpoint = process.env.EXPORT_ENDPOINT
const exportResponse = await fetch(exportEndpoint, {
  headers: { 'accept': 'application/x-tar' }
})
await validateExport(exportResponse.blob())  // note blob() is async, so this is taking a Promise as input
// { valid: true, errors: [] }
