Limit Radish RESP bulk input sizes for unauthenticated connections

Redis recently implemented a response to a CVE which allows for unauthenticated users to craft RESP requests which consume a lot of memory. Our implementation suffers from the same problem.

For example, a command input starting with `*<MAX_INT>` would result in the JVM trying to allocate an array of size `MAX_INT`. 

We need to be able to provide the same safeguards as Redis does.
