Add check against prior PgOSM Flex version with replication

[rustprooflabs]

Details

Closes #343.

When there is not a prior import tracked in osm.pgosm_flex, there is no change to output/operation. When using --replication after the initial run, details of the prior import version will be displayed. Same version:

2023-11-22 15:00:09,524:INFO:pgosm-flex:import_mode:Prior import used PgOSM Flex: 0.10.2
2023-11-22 15:00:10,580:INFO:pgosm-flex:helpers:PgOSM Flex version:  0.10.2-822ddd3

Example when PgOSM Flex used now is newer than prior.

2023-11-22 15:07:24,999:INFO:pgosm-flex:import_mode:Prior import used PgOSM Flex: 0.10.1
2023-11-22 15:07:25,020:INFO:pgosm-flex:helpers:PgOSM Flex version:  0.10.2-822ddd3

If the version used for prior import was newer, informs the user and stops.
