New Features
- New command `seismic +clustup` ("cluster update") lets you increase the number of clusters in a clustered dataset _after_ you have already run clustering.
- This feature is most useful if you want to check if clustering works with a small number of clusters (e.g. 2) and then try with more clusters (without needing to rerun clustering with 2 clusters).
- Only the new clusters run; previously run clusters are kept, saving time and energy.
- New clusters are simply appended to the report, the batches, and the counts file, as if you had run clustering with that number of clusters initially.
- There is no limit (beyond computer resources) to the number of clusters you can add, or to the number of times you can run `seismic +clustup` on the same dataset.
Bug Fixes
- Fixed bug where NaNs would not be removed properly when calculating normalized RMSDs.
