scripts: Prefer .a for single entry namedtuples
- CsvInt.x -> CsvInt.a - CsvFloat.x -> CsvFloat.a - Rev.x -> Rev.a This matches CsvFrac.a (paired with CsvFrac.b), and avoids confusion with x/y variables such as Tile.x and Tile.y. The other contender was .v, since these are cs*v* related types, but sticking with .a gets the point across that the name really doesn't have any meaning. There's also some irony that we're forcing namedtuples to have meaningless names, but it is useful to have a quick accessor for the internal value.
