Enable more languages for language detection

The `lingua` crate v1.8.0 detects language much faster than before, but
requires 3 times as much disk space in the Tp-Note binary.
Therefor, this release:

* Ships approximately the language detection data for only half of the
  77 available languages (see `features` for the `lingua` crate in
  `Cargo.toml`).
* Enables by default all available languages as search candidates.
  (Can be configured with `filter.get_lang.language_candidates`,
  e.g. `filter.get_lang.language_candidates = [ "en", "fr", "de" ]`).
