Executions of Studio flows

Operations: `list`, `create`, `fetch`, `update`, `delete`

# `create`

```elixir
@spec create(Twilio.Client.t(), String.t(), map(), keyword()) ::
  {:ok, Twilio.Resources.Studio.V1.Flow.Execution.t()}
  | {:ok, map(), map()}
  | :ok
  | {:error, Twilio.Error.t()}
```

Triggers a new Execution for the Flow

Operation: `CreateExecution` | Tags: StudioV1Execution

## Required Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `From` | string (phone-number) | The Twilio phone number to send messages or initiate calls from during the Flow's Execution. Available as variable `{{flow.channel.address}}`. For SMS, this can also be a Messaging Service SID. |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `To` | string (phone-number) | The Contact phone number to start a Studio Flow Execution, available as variable `{{contact.channel.address}}`. |
## Optional Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `Parameters` | string | JSON data that will be added to the Flow's context and that can be accessed as variables inside your Flow. For example, if you pass in `Parameters={"name":"Zeke"}`, a widget in your Flow can reference the variable `{{flow.data.name}}`, which returns "Zeke". Note: the JSON value must explicitly be passed as a string, not as a hash object. Depending on your particular HTTP library, you may need to add quotes or URL encode the JSON string. |
