* p2w-sdk: Use wasm in the JS package, detect bundler/node via `window`

This commit makes sure that our wasm usage is more robust. We ensure
that the JSON representation renders all important numbers in their
string decimal form. b

Pyth2wormhole relay example

IMPORTANT: This is not ready for production.

This package is an example Pyth2wormhole relayer implementation. The main focus is to provide an automated integration test that will perform last-mile delivery of Pyth2wormhole price attestations.

How it works

Relayer recap

When attesting with Wormhole, the final step consists of a query for the guardian-signed attestation data on the guardian public RPC, followed by posting the data to each desired target chain contract. Each target chain contract lets callers verify the payload's signatures, thus proving its validity. This activity means being a Wormhole relayer.

How this package relays attestations

p2w-integration-observer is a Node.js relayer script targeting ETH that will periodically query its source-chain counterpart for new sequence numbers to query from the guardians. Any pending sequence numbers will stick around in a global state until their corresponding messages are successfully retrieved from the guardians. Later, target chain calls are made and a given seqno is deleted from the pool. Failed target chain calls will not be retried.
