Events for `Ethers.Contracts.ERC20`

# `approval`

```elixir
@spec approval(Ethers.Types.t_address() | nil, Ethers.Types.t_address() | nil) ::
  Ethers.EventFilter.t()
```

Create event filter for `Approval(address owner, address spender, uint256 value)`

For each indexed parameter you can either pass in the value you want to
filter or `nil` if you don't want to filter.

## Parameter Types (Event indexed topics)

These are non-indexed topics (often referred to as data) of the event log.

 - value: `{:uint, 256}`

```elixir
@spec transfer(Ethers.Types.t_address() | nil, Ethers.Types.t_address() | nil) ::
  Ethers.EventFilter.t()
```

For each indexed parameter you can either pass in the value you want to
filter or `nil` if you don't want to filter.
