Module error 

Error and diagnostic plumbing.

Two layers, deliberately:

• Diagnostic — a located, coded message about the source (the user’s tzdata). These are what a tzdata author wants to read.
• Error — the crate’s Result error. It either wraps a diagnostic (most parse and compile failures carry one) or describes an environmental failure (I/O, an unusable configuration, a failed oracle invocation).
