client: improved returns, debugging output

[bobheadxi]

🎟️ Ticket(s): Closes #236

---

👷 Changes

oops... this turned out bigger than expected 😓

see #236 for context on this change

• client returns are no longer http.Response, but relevant structures instead
• to replace the loss of verbosity, a new --debug flag is now available to get debug output from the client
• client's user functions are now in UserClient, which you can get using client.Client.GetUserClient()
• improved use of context.Context for cleanliness of closure
• marginally improved tests
