I prematurely upgraded to Geth 1.14.5, which causes `plugeth-statediff` modules not to match `plugeth`. This is the simplest solution until Plugeth merges Geth 1.14+.
Reviewed-on: #7
- Add `postmerge1` chaindata
- Rename `small*` chaindata to `premerge*`
- Move chains into `chains` sub package (avoids having a non-data directory named `chaindata`)
- Add unit test Gitea workflow
- Update geth to 1.14.5
