crunchyroll-go v2.1.0

🖥️ CLI

• Add default useragent for requests. Can be overwritten with the --useragent flag.
• Add debug message (db30b9e) when the download fails because no episode could be found (related / causing issue: #22).
• Caching session id in separate file if only logged in permanently (with crunchy login --persistent ...) to reduce the amount of re-logging in when running multiple times.

📚 Library

• Deprecate ParseVideoURL(...) and ParseEpisodeURL(...) and recommended ParseBetaSeriesURL(...) and ParseBetaEpisodeURL(...) instead. Beta url are much safer to use and one day they (probably) will replace crunchyroll classic urls at all. The deprecated methods will stay in the library until only beta urls are supported by crunchyroll itself.
• Optimize FindEpisodeByName(...) since FindVideoByName(...) were deprecated because its results are sometimes not accurate (#22).
