agate: csvlook erroring with unsupported operand error

Created by: zorab47

Executing csvlook on this file gives an unsupported operand error, however, other CSV tools can open file without error.

$ csvlook test.csv.log
unsupported operand type(s) for -: 'int' and 'str'

$ csvlook --version
csvlook 1.0.2

Attached is the CSV causing the problem (renamed to .log to allow the upload). What additional information can I provide?
