Add metadata to tables, fix slow start

benjeffery commented 3 weeks ago

Whilst working on other things and testing with a large TS I noticed that we are objectifying all the mutations several times. This means for a large TS start up can take way too long. I've reworked the loading code to not use the tskit row objects. Hopefully this is a good compromise. I've also added metadata to the table views.
