[WIP] Pr/drozdziak1/p2w batching/5e704f8b (#877)

* ethereum: p2w contract -> p2w emitter, fill in essential envs

Change-Id: I6fa9364a96738d2cc02ec829a31fedba0586d8e8

commit-id:0a56f1f8

* Add p2w-relay, a p2w-sdk integration test

commit-id:6bfab639

* p2w-sdk: Expand README

Change-Id: I17cb547d6aaddc240588923561c26d11a787df2e

commit-id:6ebd6a22

* p2w-sdk: don't build ETH contracts, only the types

Change-Id: I7cbd18328227700635d7688aa24a9671e8919fcd

commit-id:adf079f7

* p2w: configurability and sane envs

commit-id:f10fd90e

* Solitaire: Implement Option<T> support in structs

commit-id:31aa12d6

* bridge/governance.rs: Stop pestering about EMITTER_ADDRESS

commit-id:d5bd7234

* p2w-attest: price batching

This commit introduces support for multiple Pyth product/price pairs
per call. The initial maximum batch size is 5 and is enforced using a
`P2W_MAX_BATCH_SIZE` constant.

solana/pyth2wormhole/program:
* On-chain batching logic
* Batch message parsing logic

solana/pyth2wormhole/client:
* Off-chain batching logic - divides any number of symbols into
largest possible batches
* Use a multi-symbol config file instead of CLI arguments

third_party/pyth/p2w-sdk:
* Expose batch parsing logic

third_party/pyth/p2w-relay:
* Comment out target chain calls until ETH contract supports batching
* Test the batch parsing function

third_party/pyth/p2w_autoattest.py:
* Generate and use the symbol config file  with pyth2wormhole-client

third_party/pyth/pyth_publisher.py:
* Add a configurable number of mock Pyth symbols
* Adjust HTTP endpoint for multiple symbols

commit-id:73787a61

* p2w-attest: mention attestation size in batch

This commit ensures that no matter the attestation format, a batch
will never contain attestations of different sizes. This guarantee
enables forward compatibility by adding new constant-size fields at
the end of a batch at all times. An older implementation will simply
not consume the remaining newer values while respecting the stated
batch member alignment.

commit-id:210da230

* pyth2wormhole-client: use fresh blockhashes, harden batch errors

This commit makes sure we don't have to deal with expired transactions
due to stale blockhashes. The problem existed with larger symbol
configs as well as on Solana mainnet. Additionally, the attestation logic
now treats transaction errors as non-critical - a failure for a batch
does not prevent attestation attempts for batches farther in the queue

+# 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-relay` 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.

 This project contains a library for interacting with pyth2wormhole and adjacent APIs.
 
 # Install
-Firstly, please follow instructions in `//bridge_ui/README.md` where
-`//` is the Wormhole project root.
+For now, the in-house dependencies are referenced by relative
+path. The commands below will build those. For an automated version of
+this process, please refer to `p2w-relay`'s Dockerfile and/or our [Tilt](https://tilt.dev)
+devnet with `pyth` enabled.
 
-# Usage
+```shell
+# Run the commands in this README's directory for --prefix to work
+$ npm --prefix ../../../ethereum ci && npm --prefix ../../../ethereum run build # ETH contracts
+$ npm --prefix ../../../sdk/js ci # Wormhole SDK
+$ npm ci && npm run build # Pyth2wormhole SDK
