feat: Implement Pipeline support

Adds support for pipelines, allowing streams to be chained together and
transformed.
This includes new types for `PipeStream` and `SourceAdapter`, along with
modifications
to the `Environment` to manage pipeline execution. A new example
`pipeline.myc`
demonstrates its usage.
