small

Problem

As we fully transition to octopus, it's time to strip out the simularium-engine specific code that is no longer useful Link to story or ticket

Solution

• got rid of the --octopus commandline option, as that will now be the assumed platform
• got rid of the useOctopus option, as that will now be the assumed platform

A website PR will need to be made after this, updating their NetConnectionParams to remove useOctopus
