Update subxt requirement from 0.34 to 0.37

[dependabot]

Updates the requirements on subxt to permit the latest version.

Release notes

Sourced from subxt's releases.

v0.37.0

[0.37.0] - 2024-05-28

This release mainly adds support for the sign extension CheckMetadataHash and fixes a regression introduced in v0.36.0 where the type de-duplication was too aggressive and lots of the same type such as BoundedVec was duplicated to plenty of different types such as BoundedVec1, BoundedVec2, .. BoundedVec.

Added

• Implemented sign_prehashed for ecdsa::Keypair and eth::Keypair (#1598)
• Add a basic version of the CheckMetadataHash signed extension (#1590)

Changed

• Remove derive_more (#1600)
• chore(deps): bump scale-typegen v0.8.0 (#1615)

[0.36.1] - 2024-05-28 [YANKED]

Yanked because the typegen changed, it's a breaking change.

[0.36.0] - 2024-05-16

This release adds a few new features, which I'll go over below in more detail.

subxt-core

We now have a brand new subxt-core crate, which is #[no-std] compatible, and contains a lot of the core logic that is needed in Subxt. Using this crate, you can do things in a no-std environment like:

• blocks: decode and explore block bodies.
• constants: access and validate the constant addresses in some metadata.
• custom_values: access and validate the custom value addresses in some metadata.
• metadata: decode bytes into the metadata used throughout this library.
• storage: construct storage request payloads and decode the results you'd get back.
• tx: construct and sign transactions (extrinsics).
• runtime_api: construct runtime API request payloads and decode the results you'd get back.
• events: decode and explore events.

Check out the docs for more, including examples of each case.

A breaking change that comes from migrating a bunch of logic to this new crate is that the ExtrinsicParams trait is now handed &ClientState<T> rather than a Client. ClientState is just a concrete struct containing the state that one needs for things like signed extensions.

Support for reconnecting

We've baked in a bunch of support for automatically reconnecting after a connection loss into Subxt. This comes in three parts:

1. An RPC client that is capable of reconnecting. This is gated behind the unstable-reconnecting-rpc-client feature flag at the moment, and
2. Handling in the subxt Backends such that when the RPC client notifies it that it is reconnecting, the backend will transparently handle this behind the scenes, or else pass on a DisconnectedWillReconnect error to the user where it cannot. Note that the individual LegacyRpcMethods and UnstableRpcMethods are not automatically retried on reconnection. Which leads us to..
3. A couple of util helpers (subxt::backend::retry and subxt::backend::retry_stream) which can be used in conjunction with a reconnecting RPC client to make it easy to automatically retry RPC method calls where needed.

We'd love feedback on this reconnecting work! To try it out, enable the unstable-reconnecting-rpc-client feature flag and then you can make use of this like so:

use std::time::Duration;
