Convenience method to wrap json-schema validation into a single function.

The single API method exported: `isValid(schema, data)`, does three things:

1. Dereference the schema to resolve all external references
2. Validate the resulting fullSchema
3. Validate the data against the fullSchema.

## Usage

### API

```typescript
/**
 * Provides a convenience interface to validate a data object
 * against a dereferenced schema object.
 *
 * Throws a SchemaError if either the schema or data is not valid.
 * SchemaError provides an `errors` property, detailing individual
 * violations.
 *
 * @async
 * @param schema schema to validate data against
 * @param data data to validate
 * @returns Promise<boolean>
 */
export declare const isValid: (schema: any, data?: any) => Promise<boolean>;

```

### CLI

```bash
  Usage: data-check [options]


  Options:

    -V, --version          output the version number
    -d, --data <data>      data to validate {json, yaml}
    -s, --schema <schema>  schema to use for validation {json, yaml}
    -h, --help             output usage information
```

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.
