AWS SDK for Javascript v3 Upgrade

Feature Request

Is your feature request related to a problem? Please describe. There is a warning when running aws-cost that AWS SDK for Javascript v2 will be entering maintenance mode in 2023.

Describe the solution you'd like Upgrade to AWS SDK for Javascript v3. Having a quick look through the codebase this shouldn't be a massive undertaking but does depend on experience with v3, especially in Typescript given it's a lot more modular now. This may also help to resolve #5 and #6 as I believe v3 has better support for using environment variables to load AWS credentials.

Describe alternatives you've considered N/A

I may well have the time at some point so I may try and get a PR up at some point but not committing to anything just now.
