Output file path from CLI usage

### Prerequisites - [✓] I'm using the last version. - [✓] My node version is the same as declared as `package.json`. ### Subject of the issue Is there any way to set the output file path and name as the result of the `browserless` cli? ### Steps to reproduce ```sh npm install -g @browserless/cli browserless screenshot https://github.com/ ``` It results in a screenshot of the Github on my Terminal but I'd like to set a specific file name and destination. E.g.: ```sh browserless screenshot https://github.com/ > github.png ``` or ```sh browserless screenshot https://github.com/ --output github.png ```
