implement r2 bulk put

[vicb]

Add support for wrangler r2 bulk put bucket-name --filename list.json

// list.json
[
  { "key": "/path/to/obj", "file": "/path/to/file"},
  // ...
]

It supports the same options as wrangler r2 object put, minus --file and --pipe and plus --concurrency

Notes for reviewers:

• r2/helpers.ts has been splitted into different files r2/helpers/<what.ts>
• helpers outside of object.ts (used by the bulk command) are unchanged
• there is one new helper bulk.ts

Future work (will create issues before merging this PR)

• allow to override metadata for individual object
• wrangler r2 bulk put bucket-name --folder /path/to/folder to upload a folder to R2
• wrangler r2 bulk get bucket-name --folder /path/to/folder to download a folder from R2

TODO:

• update for p-queue v9
• e2e tests
• local unit tests
• add a changeset
