* Split state group persist into seperate storage func * Add per database engine code for state group id gen * Move store_state_group to StateReadStore This allows other workers to use it, and so resolve state. * Hook up store_state_group * Fix tests * Rename _store_mult_state_groups_txn * Rename StateGroupReadStore * Remove redundant _have_persisted_state_group_txn * Update comments * Comment compute_event_context * Set start val for state_group_id_seq ... otherwise we try to recreate old state groups * Update comments * Don't store state for outliers * Update comment * Update docstring as state groups are ints
