Description

Should plan on using https://github.com/minio/minio-java to maximize portability with other s3 compatible object stores.

Will need to accept client ID and secret as environment variables so I don't want a bunch of call sites in itzg/minecraft-server to need to be modified. Using env vars is quite typical in this codebase via picocli.

Contributor guide

Research direction
Investigate the implementation of the 'get' and 'mcopy' subcommands and how environment variables are loaded via picocli. Research the minio java client for supporting s3:// URLs.
