DelayDense runs into error if max_delay is set to more than the actual delay value

[bamsumit]

Describe the bug DelayDense runs into error if max_delay is set to more than the actual delay value

To reproduce current behavior Steps to reproduce the behavior:

1. When I run this code (add code or minimum test case) ...

   synapse = DelayDense(
               weights=np.eye(5),
               delays=np.eye(5) * 10,
               max_delay=62,
           )

2. Runs into runtime error due to mismatch between DA buffer and delayed synapse computation.

Expected behavior A clear and concise description of what you expected to happen.
