Go SDK for Symbl.ai v0.1.8

This release marks the initial implementation of Symbl.ai's Go SDK. This patch release continues to add important functionality for usability, unlocking capabilities, and enabling use cases.

IMPORTANT: I would consider this project in a pre-release status. Since this is the first release, we currently reserve the right to make breaking API changes at this time.

Significant Updates:

• Ability to add query params to API calls
• Implements an Async API Callback Interface
• Reuse REST Bearer Token for Creating New Clients
