* Support updated OT 0.14 / tracing-OT 0.12 crate versions
Add support for opentelemetry 0.14 and tracing-opentelemetry 0.13.
Make corresponding changes to the features, docs, and examples.

reorganization had to be done for the internal modules.
Addresses issue #22.

Add two new error types implementing ResponseError, as required, for our extractors.
