feat: add anchor bindings anchor-lang

[mgild]

This change adds wrapper bindings for the AddressLookupTable program and AddressLookupTable Account.

Usage:

#[derive(Accounts)]
pub struct Action<'info> {
    pub lut_program: Program<'info, AddressLookupTable>,
    pub lut_signer: Signer<'info>,
    pub lookup_table: Account<'info, AddressLookupTableAccount<'info>>,
}

Tests:

cd lang
cargo build

[vercel]

@mgild is attempting to deploy a commit to the coral-xyz Team on Vercel.

A member of the Team first needs to authorize it.

This has been requested before, so thank you for adding this!

It would be very helpful to have some tests for these types. They don't need to be very complicated; just some tests to check compilation and basic functionality. Compilation tests are especially important given how easy it is to miss the idl-build feature impl.

There are also a couple more issues that I mentioned in the comments, but it looks good otherwise.

[acheroncrypto]

Thanks. We also need to add the tests to the workflow file to make them run in CI.

The test folder looks like you may have uncommitted changes because there are unused keypairs and definitions (the test itself also doesn't work). I left some comments for those issues.

Lastly, this feature surely deserves a mention in the CHANGELOG — could you add an entry?

[acheroncrypto]

It wouldn't hurt to have this, but does it make sense to have it when the account is always going to be immutable in our usage?

[acheroncrypto]

Nit: other tests use the current version of the repo (0.30.1) here, so it would be nice to keep things consistent when possible.

Suggested change

	"version": "0.24.0",
	"version": "0.30.1",

[acheroncrypto]

It doesn't look like this is being used anywhere. If so, could you remove it?

Suggested change

use crate::program::AddressLookupTableTest;

[acheroncrypto]

Errors also don't seem to be used. Please remove if that's the case.

Suggested change

	#[error_code]
	pub enum CustomError {
	InvalidProgramDataAddress,
	AccountNotProgram,
	}

[acheroncrypto]

This syntax has been deprecated for a long time, and we plan to remove it soon — could you use the newer syntax?

Suggested change

	const tx = await program.rpc.test({
	accounts: {
	authority: provider.wallet.publicKey,
	lutProgram: lutProgramAddress,
	table: lutProgramAddress, // Just a dummy value. fix
	},
	signers: [settings],
	});
	const tx = await program.methods
	.test()
	.accounts({ table: lutProgramAddress })
	.rpc();

Also, settings don't seem to be defined anywhere.
