Is your feature request related to a problem? Please describe.
The smartsheets documentation states that the SDKs have support for the OAuth authentication workflow, but methods for acquiring an access token have circular dependencies that also require the use of an API access token. The token generation functionality is also tightly coupled with the smartsheets objects without supporting the generation of an Authentication Code and requiring the use of a third party library for this operation.

Describe the solution you'd like
Decoupling of the OAuth mechanism from the smartsheets object, allowing for the creation of an access token before the instantiation of the smartsheets object, support for Authentication Code generation or use of/plugin setup for use of a third party library that supports OAuth2.0
