Release v0.35.0

The release mostly fixes funding during the audit and integration with the bridge. But the release also contains some new features like:

#486: Adds ed25519 signature verification and secp256r1 signature recovery to fuel-crypto, and corresponding opcodes ED19 and ECR1 to fuel-vm.
#500: Introduced ParallelExecutor trait
and made available async versions of verify and estimate predicates.
Updated tests to test for both parallel and sequential execution.
Fixed a bug in transaction/check_predicate_owners.

#506: Added new Mint and Burn variants to Receipt enum.
It affects serialization and deserialization with new variants.

#506: The mint and burn
opcodes accept a new $rB register. It is a sub-identifier used to generate an
AssetId by this rule.
This feature allows having multi-asset per one contract. It is a huge breaking change, and
after this point, ContractId can't be equal to AssetId.

The conversion like AssetId::from(*contract_id) is no longer valid. Instead, the ContractId implements the ContractIdExt trait:
```
/// Trait extends the functionality of the `ContractId` type.
pub trait ContractIdExt {
    /// Creates an `AssetId` from the `ContractId` and `sub_id`.
    fn asset_id(&self, sub_id: &Bytes32) -> AssetId;
}
```
#506: The mint and burn
opcodes affect the receipts_root of the Script transaction.

#486: Removes apparently unused Keystore and Signer traits from fuel-crypto. Also renames ECR opcode to ECK1.

#500: Fixed a bug where MessageCoinPredicate wasn't checked for in check_predicate_owners.

#502: The algorithm used by the
binary Merkle tree for generating Merkle proofs has been updated to remove
the leaf data from the proof set. This change allows BMT proofs to conform
to the format expected by the Solidity contracts used for verifying proofs.
#503: Use correct amount of gas in call
receipts when limited by cgas. Before this change, the Receipt::Call could show an incorrect value for the gas limit.
#504: The CROO and CSIZ opcodes require
the existence of corresponding ContractId in the transaction's
inputs(the same behavior as for the CROO opcode).
#504: The size of the contract
was incorrectly padded. It affects the end of the call frame in the memory,
making it not 8 bytes align. Also, it affects the cost of the contract
call(in some cases, we charged less in some more).
#504: The charging for DependentCost
was done incorrectly, devaluing the dep_per_unit part. After the fixing of
this, the execution should become much more expensive.
#505: The data field of the Receipt
is not part of the canonical serialization and deserialization anymore. The SDK should use the
Receipt type instead of OpaqueReceipt. The Receipt.raw_payload will be removed for the
fuel-core 0.20. The data field is optional now. The SDK should update serialization and
deserialization for MessageOut, LogData, and ReturnData receipts.
#505: The len field of the Receipt
is not padded anymore and represents an initial value.
