Provide a convenient way to fix bad values in telemetry archive

Provide a documented and user-friendly way to permanently fix bad values that get into the archive, for instance in #47.  This will require at least:

- Fix the MSID, 5min and daily stat `*.h5` files
- Possibly just fix MSID and have a mechanism to re-run 5min and daily stats.
- Permanent archive of fixes to allow for re-applying all fixes in case of reprocessing.
- Mechanism to apply fixes to both HEAD and OCC archives.
