Update subxt requirement from 0.29.0 to 0.35.3

[dependabot]

Updates the requirements on subxt to permit the latest version.

Release notes

Sourced from subxt's releases.

v0.35.3

[0.35.3] - 2024-04-11

Another bug-fix release that substitutes BinaryHeap for Vec in the same way that we do for BTreeMap/Set to avoid issues with the Ord constraint on the generic type (because this may be a generated type, and we don't automatically apply Ord to generated types).

[0.35.3] - 2024-04-11

Another bug-fix release that substitutes BinaryHeap for Vec in the same way that we do for BTreeMap/Set to avoid issues with the Ord constraint on the generic type (because this may be a generated type, and we don't automatically apply Ord to generated types).

[0.35.2] - 2024-04-09

This is a small patch release that fixes the storage key decoding. Previously, we assumed the length of the hash of the storage prefix or entry name was 8 bytes, however it is 16.

[0.35.1] - 2024-04-03

This is a small patch release that adds support for BinaryHeap in the codegen/subxt-cli which wasn't supported by scale-typegen. This was discovered because the most recent metadata in polkadot are now utilizing BinaryHeap.

[0.35.0] - 2024-03-21

This release contains several fixes, adds no_std support to a couple of crates (subxt-signer and subxt-metadata) and introduces a few quality of life improvements, which I'll quickly cover:

Reworked light client (#1475)

This PR reworks the light client interface. The "basic" usage of connecting to a parachain now looks like this:

#[subxt::subxt(runtime_metadata_path = "../artifacts/polkadot_metadata_small.scale")]
pub mod polkadot {}
use subxt::lightclient::LightClient;
// Instantiate a light client with the Polkadot relay chain given its chain spec.
let (lightclient, polkadot_rpc) = LightClient::relay_chain(POLKADOT_SPEC)?;
// Connect the light client to some parachain by giving a chain spec for it.
let asset_hub_rpc = lightclient.parachain(ASSET_HUB_SPEC)?;
// Now, we can create Subxt clients from these Smoldot backed RPC clients:
let polkadot_api = OnlineClient::<PolkadotConfig>::from_rpc_client(polkadot_rpc).await?;
let asset_hub_api = OnlineClient::<PolkadotConfig>::from_rpc_client(asset_hub_rpc).await?;

This interface mirrors the requirement that we must connect to a relay chain before we can connect to a parachain. It also moves the light client specific logic into an RpcClientT implementation, rather than exposing it as a subxt::client::LightClient.

Typed Storage Keys (#1419)

This PR changes the storage interface so that, where possible, we now also decode the storage keys as well as the values when iterating over storage entries:

#[subxt::subxt(runtime_metadata_path = "../artifacts/polkadot_metadata_small.scale")]
pub mod polkadot {}
// Create a new API client, configured to talk to Polkadot nodes.
let api = OnlineClient::<PolkadotConfig>::new().await?;
</tr></table>
