decide on wiring table format and mechanisms

[rerpha]

Wiring tables is a concept that still exists however the format is now different (.csv as opposed to the old wiring table format).

The options that we're considering are:

• change .csv to align with the old format
• write a service/script to convert to/from .csv
• keep the two formats separate, acknowledging that they will not be backwards or forwards compatible

acceptance criteria

• choose one
• create more tickets to actually implement anything needed
