Rust pop-quiz: Aave market data-entry

#Rust pop-quiz!

The format of an @AaveAave money-market scrape ('dashboard') is atrocious! i.e.:

14,847.59

$

411.78

2.43

%

rendering the ./data_entry tool impotent.

'fix' this problem.

Hint: you can fix the scanner,

or: you can fix the input data. 

• answer: It turns out that we don't need data-entry for @AaveAave (yet), and that @GranaryFinance, @BenqiFinance, and @GeistFinance all follow (basically) the same format, so: did a wee bit o' generalization to ./data_entry (using scan-windows), and we good.
