[FEATURE] Localization in other languages

[amir16yp]

Is your feature request related to a problem? Please describe.
I think this program might benefit from localization into different languages

Describe the solution you'd like
Instead of hardcoding english, create a localization json or similar data structure, and allow users to contribute their own translations with key pair values

Additional context
This program is really popular among russian and spanish speakers. This video about arnis in russian has 40k views. This one in spanish has 200k. I also saw one of the forks being simply a translation into chinese.

Woah, didn't know about the Spanish >200k video until now - really cool!
Yes, I really like that idea! I think English, Spanish, Russian and German seems to be most asked for as of now.

I'll close this issue for now - feature is implemented and already merged into main!
Just want to get a bit more feedback from native speakers until I include it in a release. I'm using #193 as a feedback thread for this. Thanks a lot Amir :)
