Currently only configurable via manual `data/config/config.ini`
text edition.
New configurable values are `series_scores` and `movie_scores`.
For each config section, the sum of the config values (except hash)
must be equal to the hash value plus one (1), otherwise default
values will be used (notified via debug log).
Hash values are not meant to be modified; the value is shown in
`config.ini` for reference. Modifying hash values would imply
breaking Bazarr's score logic.
