auth
auth/memstore.go
Add an endpoint to validate and register profiles. Add a newProfileRequest object that defines the user-specified properties of a new Profile. Add a helper that validates a newProfileRequest and modifies it for sanitization, mostly just removing leading and trailing whitespace. Add MaxNameLength, MaxUsernameLength, and MaxEmailLength constants to hold the maximum length for those properties. Add errors to be returned when a users attempts to log in with a profile that is compromised or locked. Add the bare bones of a CreateProfileHandler that validates a profile registration request adn uses it to create a Profile and at least one Login. Create a requestError struct that is used for returning API errors, along with constants for the slugs we'll use to signal those errors.
