Draft: Initial attempt at naive debounce for login api

[hgoscenski]

Update maybeLogin to check last login time and perform exponential backoff, up to 5 minutes. Debounce will reset back to 1s after 12 hours has passed, to prevent users from being stuck with a 5 minute polling interval in the case of a login.

In the event a user's password/api key do expire or are changed naturally, then during the config update the bridge/homebridge will be prompted to restart, resetting the debounce and allowing them to login promptly.

Should ameliorate issues in #6

Update example to have parameters provided via env var.
Added .env.sample
Update sleep function to have correctly named parameter

Example can be run via node --env-file=.env example

Example run with loginCheck(4) and persisted token temporarily disabled.

I like that changes. I will also clean up the MFA code.
