container: fetch: prices: crypto: mobula: isolate given year

- Will now only parse given year (or 'all', if given).

  * No longer parses all subsequent years after given year
    (unless 'all' is given).

- Now prints most recent daily average for given year instead of most
  recent daily average for current year.
