v0.2.0: Add v1Dashboards list/get APIs

This version includes Dashboard types which were originally generated by Datadog's OpenAPI generator. The definitions are mangled to fit into the lighter footprint expected of Deno modules.

There's also a new example which uses the v1Monitors Search API to paginate through all APM monitors in the Datadog account.

v0.1.4: Deno 1.9+ compatibility

Includes #2, fixing an error with GET requests that was introduced in Deno 1.9.1

Thanks to @rodmatos for the contribution.

v0.1.3: Add v1Events for submitting events

Implements the "Post an event" endpoint to allow uploading individual rich-text events to Datadog for viewing & monitoring.
