[Task]: Implement FileIO SchemaTransform Provider

### What needs to happen?

The output of this task is a [TypedSchemaTransformProvider](https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/schemas/transforms/TypedSchemaTransformProvider.java) extension for reading from and writing files using the FileIO.Read and FileIO.Write transforms, respectively.

Briefly described, a Read and Write configuration informs a [TypedSchemaTransformProvider](https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/schemas/transforms/TypedSchemaTransformProvider.java) extension for details on how to build a corresponding FileIO.Read and FileIO.Write [SchemaTransform](https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/schemas/transforms/SchemaTransform.java).

See [BigQuerySchemaTransformReadProvider](https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/BigQuerySchemaTransformReadProvider.java) and [BigQuerySchemaTransformWriteProvider](https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/BigQuerySchemaTransformWriteProvider.java) for an example design pattern.
