spike: generate call report PDF with static values

[adamdecaf]

There's a template PDF that needs to be submitted. This is the "Call Report" required by regulations.

Let's try and fill in the fields (yellow boxes) with static values ($1.00 or something) just to make sure we can. I've only worked with PHP pdf libraries, so this'll be new for everyone.

Call Report Search: https://cdr.ffiec.gov/public/ManageFacsimiles.aspx (try Wells or Chase)

I found some Go/PDF projects on Github, but haven't tried any of them.
