Is your feature request related to a problem? Please describe.

When working with the CLI I usually use the Tab key to complete a partially entered command. However this doesn't work with Gushio scripts.

Describe the solution you'd like

Ideally, Gushio script autocompletion should work for both the gushio executable itself and the script I want to invoke. This means I should be able to autocomplete for example:

gushio --verb|
gushio --verbose 

gushio my_script.js my_parti|
gushio my_script.js my_partial_argument 

./my_script.js my_parti|
./my_script.js my_partial_argument 

I guess adding autocompletion to remote scripts could be quite hard and I don't think is necessary

Additional context

Autocompletion is a feature specific of some interactive shells like Bash and ZSH. However, PowerShell also has autocompletion but I have still not found a js autocompletion package supporting it.
