Change the way to do unit testing

[rayriffy]

Credit card statement is not a thing that should be publicly shared. There's some possible improvements.

• Create separate unit testing for PDF reader, using dataset that not related to credit card statement. (i.e. mock table pdf)
• Mock data for credit card parser can be sampled out as a result that has been extracted from pdf reader

const citiSamplePage: string[][] = [
  [
    "130",
    ".69",
    "07",
    "FEB",
    "02",
    "FEB",
    "PIXIV",
    "FANBOX",
    "TOKYO",
    "JP",
    "YEN",
    "500",
    ".00",
   ...
  ]
]
