Find 'em, Fix 'em / Find/Fix/Data conversion and bridge programs

#### Separate conversion, scrubbing, & bridging program

- Before conversion: the forward bridge works by windowing.
- After conversion: the backward bridge works by truncation.
- During conversion:
  - scrub invalid and reserved values out of dates
  - change data store organization, if appropriate
  - expand dates or encode into existing fields
  - reload data store due to date embedded in key, if appropriate
