9c8319e minor - Remove interface usage from @appsignal/types

All Node.js-specific interfaces from the types package are now defined inside the nodejs core package. There's still a dependency from types package for common types as Func, HashMap, and HasMapValue.

With this change, we keep taking advantage of interfaces, but now they're defined in a place where they're used.

723b98d minor - Add rootSpan and setError helpers.

Errors added to child spans are ignored by the agent. Now the rootSpan is always accessible from the tracer object as well as setError. The setError function allows to track errors on demand and they will be always attached to the main current span, so they don't get ignored by the agent.

f0256d3 patch - Bug fix in custom timestamp calculation

1f182a4 patch - Deprecate the addError function on the Span interface. Instead use the Tracer's setError function to set the error on the root span.

96df8a4 patch - Add sendError helper to Tracer object.

This new helper allows you to track an error separately from any other span inside the current context. Or use it to set up in your own error handling to report errors in a catch-statement if no performance monitoring is needed.

try {
  // Do complex stuff
} catch (error) {
  appsignal.tracer().sendError(error, span => {
    span.setName("daily.task"); // Set a recognizable action name
    span.set("user_id", user_id); // Set custom tags
  });
}

patch - Update @appsignal/nodejs-ext dependency to 2.0.1.
