* Make SpanContext Immutable
* Adds NewSpanContext() constructor and SpanContextConfig{} struct for
constructing a new SpanContext when all fields are known
* Adds With<field>() methods to SpanContext for deriving a SpanContext
with a single field changed.
* Updates all uses of SpanContext to use the new API
Signed-off-by: Anthony J Mirabella <a9@aneurysm9.com>
* Update CHANGELOG.md
Signed-off-by: Anthony J Mirabella <a9@aneurysm9.com>
* Add tests for new SpanContext constructor and derivation
Signed-off-by: Anthony J Mirabella <a9@aneurysm9.com>
* Address PR feedback
* Fix new uses of SpanContext from main
