Lingua 1.3.0

Features

• The language model dependencies are separate Cargo features now. Users can decide which languages shall be downloaded and used in the library. (#12)

Improvements

• The code that does the lazy-loading of the language models has been refactored significantly, making the code more stable and less error-prone.

Bug Fixes

• In very rare cases, the language returned by the detector was non-deterministic. This has been fixed. Big thanks to @asg0451 for identifying this problem. (#17)
