feat(statics): add Hemi EVM chain support

Add Hemi L2 EVM chain to BitGoJS statics:
- Add HEMI to CoinFamily and UnderlyingAsset enums
- Create Hemi/HemiTestnet network classes (chain IDs: 43111/743111)
- Add hemi/themi coin entries with EVM features
- Add explorer API URLs to environments
- Update test fixtures
