To generate a standalone certificate, we need to map an order / MTC serial number to a subtree that (a) contains that serial number and (b) will eventually get a mirror signature written to it by the mtpublisher. Add a new table to store (up to) two subtrees per checkpoint, covering the entries between that checkpoint and the previous one. Also add an `mtcSubtreeID` field to order objects. Adds more documentation about what's stored in the `checkpoints.mirrorSignature` and `checkpoints.mtcaSignature` fields, with a TODO to change what's stored there.
