Add support for Romanian similar to @beradrian contribution.

I can assist here if needed. Besides translating the resource file is there anything else that should be done? Are there any tests?

[jmrozanec]

@beradrian We currently have tests only for English language. If you can contribute the translations and add some tests, that would be great. Thank you for looking into this!

Take a look here: https://github.com/beradrian/cron-utils/tree/ro-ro

The only problem is that new messages have to be defined at_second, at_minute, at_hour, at_month.

Could you please make use of these in the code? If yes, I can modify the rest of the resources and tests will pass.

There will also be nice if we can have something like between_month_x_and_y and between_weekday_x_and_y. The current one works, but this will enable to have a more natural format in Romanian (possible other languages too).

@beradrian thank you for the contribution!
I agree on your proposal. To deal with it we may need to do some refactoring on how cron descriptions are being done now. Will work on this on the following days and come back with an idea / workaround. If you have any suggestions, are welcome!

@beradrian Romanian is now supported! 🚀
