Implement "LaunchPads" endpoint

***Why?***
- Implement Launch Pads endpoint as requested by [#66](#68)

***Description***
- Uses reference specified in the issue above https://docs.spacexdata.com/?version=latest#e232e64a-58a2-4bc0-af42-eb20499425cc
- Closes [#66](#68)

***Side effects/ Notes***
- Got an error when running this locally due to Faraday enforcing `.adapter` over `.use`, so had to make that change as well
