Added `break` statements for `PUT` and `DELETE` methods
Added `break` statements for `PUT` and `DELETE` methods

When specifying either `PUT` or `DELETE` HTTP method options, then the case statement will fall through and throw an exception. The Acuity API supports a handful of `PUT` and at least one `DELETE` so this would effectively prevent users from making those calls using this SDK.

This fixes the bug.
