Add functions `auth_with_link_code`, `get_ms_link_code`, and `get_ms_auth_token`. (#88)

* Add option for grabbing authentication code for Microsoft seperately. Created two new functions, one that outputs the DeviceCodeResponse and one that uses this response to authenticate an actual account.

* Added documentation and cleaned up function names. Still wondering about code repeition

* reduce code duplication, more docs, cleanup

* clippy
