BREAKING CHANGE:

- Instead of importing methods (like `bond`, `balanceTransfer`) directly from the root, the package exposes a `methods` object in the root, and this object contains all available methods organized by pallet:

```diff
- import { bond, balanceTransfer } from '@amaurymartiny/txwrapper';
+ import { methods } from '@amaurymartiny/txwrapper';

- bond(...);
- balanceTransfer(...);
+ methods.staking.bond(...);
+ methods.balances.tranfer({dest: '...', value: }, {blockHash: '0x...'});
+ methods.balances.transferKeepAlive(...);
```

- All the methods under `methods.*.*` take now 2 arguments: the first one is the actual args specific to the tx method, and the second one is `BaseTxInfo`, common to all transactions

```typescript
methods.staking.nominate({target: ['F1...']}, {blockHash: '0x..', ...});
```

- `balances::transfer` arguments has been renamed from `{to, amount}` to `{dest, value}`, to reflect the rust codebase:

```typescript
methods.balances.transfer({dest: '5....', value: 100}, {blockHash: '0x..', ...});
```

* add staking functions first commit

* fix nominate test and run linter

* use yarn docs

* move UnsignedTransaction into ./utils to enable generic tx construction

* update docs for UnsignedTransaction move

* rename TxInfo and TEST_TX_INFO to specify that they are for balance transfer

* move TxInfo into interfaces to reduce duplicate code

* make decode somewhat generic

* rename util/interfaces to util/types

* add encodings to tests

* add ss58Format as param to importPrivateKey

* add test for polkadot encoding

* add decodeSigningPayload to decode export

* linting

* linting (again)

* fix: Put function importPrivateKey in correct file

* Fix import

BREAKING CHANGE:

`generateKeypair` has been removed.

* feat: Generic `decode` also decodes unsigned

* dpcs

* Don't expose decode*

* decode doesn't decode signingPayload

BREAKING CHANGE:

- `decodeTx` has been renamed to `decodeSignedTx` for clarity

* fix: Fix keepAlive

* feat: Add decodeUnsignedTx

* Generate docs

* Export new functions

* feat: Add balances::transfer_keep_alive

* Fix logic

* Use Kusama everywhere

* Refactor: No metadataRpc in createSignedTx

* Configurable era

* Regenerate docs

* Fix test
