Update DO.py / fix solar

[alixunderplatz]

(First off: seems like historical data could be fetched for Dominican Republic, maybe you want to put that on your to-do, @corradio @robertahunt
See: http://190.122.102.21:8084/reportesgraficos/reportepostdespacho.aspx)

The DO.py parser was often failing to fetch solar correctly from the plant mapping.
I had a look at the source website, which now offers a total "solar" row that is used by the parser now.
Unfortunately, the last 2 hours of solar aren't fetched (nan is returned), but they are filled later.
Also, 2 large new coal units were comissioned last year.

• re-wrote how 'solar' is fetched
• added 2 new missing coal units "Punta Catalina" 1+2
• switched 1 type mapping from "unknown" to "oil"

Sample output:

fetch_production() ->
