Add release asset management. This includes a series of subcommands under `tea release assets`:

-  `tea release assets create <release-tag> <asset> [<asset>...]`: Upload one or more release attachments
- `tea release assets delete <release tag> <attachment name> [<attachment name>...]`: Delete one or more release attachments
- `tea release assets list <release tag>`: List Release Attachments
