Fix async genesis hash bug, add 7 missing methods, document exports

- Fix AsyncElydoraClient _prev_chain_hash from empty string to GENESIS_CHAIN_HASH
- Add list_agents, unfreeze_agent, delete_agent, get_me, issue_token, download_export, health
- Add methods to both sync and async clients
- Add corresponding response types to types.py
- Export new types from __init__.py
- Document all previously undocumented exports in README
