[Task]: Implement TextIO SchemaTransform Provider

[damondouglas]

What needs to happen?

The output of this task is a TypedSchemaTransformProvider extension for reading from and writing text files using the TextIO.Read and TextIO.Write transforms, respectively.

Briefly described, a Read and Write configuration informs a TypedSchemaTransformProvider extension for details on how to build a corresponding TextIO.Read and TextIO.Write SchemaTransform.

See BigQuerySchemaTransformReadProvider and BigQuerySchemaTransformWriteProvider for an example design pattern.
