[FEAT] [FEAT] add recurring expenses

[alessiozanutta]

Description

i think that a very nice feature that other competitors have is the possibility to insert recurring expenses.
i do not know how exactly you can implement it maintaining the simplicity of a series of entries in the jaon file, however i think this would complete this beautiful app

Thank you for the insight! This is planned, and will be implemented as soon as I have time to do so. I'm kinda waiting for #121 to finish (I'm working on it).

Closing this as duplicate of #59. Please refer to #59 for further updates!
