Rust pop-answer: Stride LSD exchange rates with github burn-rates

#Rust answer to the pop-quiz to combine @stride_zone REST API data with my own burn-rates.

./lsd.rs combines the @stride_zone REST API data with my burn rates uploaded to github as CSV, then extracted with the new ./parse_csv function.

WOOT! 🎉

Announcement: automated CSV parsing in Rust

 🦀🦀🦀cRUSTaceans!🦀🦀🦀 

I've added a new fn to my csv_utils:

parse_csv<T>(skip: usize, f: Fn, lines: Lines)

• skips <skip> lines (header
• parses CSV with <f>
• returns Vec<T> objects from CSV <lines>

This goes a long way towards automating CSV parsing for me.
