Make it easier to reorder fields in `inventory`

[tiernanmartin]

Similar columns can be grouped together by adding a common prefix (e.g., SUIT_* or FILTER_*).

Many of the columns already have common prefixes but some do not.

Once all the columns are assigned a group and a prefix the order can be changed using select() like so:

inventory %>%
  select(starts_with("[prefix string]"), 
         starts_with("[another prefix string]"), 
         everything())

I'm deciding against doing this because it will add lots of unnecessary work to the interface dev team's plate.
