Adds number recognition

[MXC48]

I think it would be a good idea for Sayboard to recognize when you pronounce a number and instead of writing it in letters writes it in numbers. For example instead of writing "a" Sayboard could type "1" For that there is the Dicio-number library which was created to already do this in the Dicio which could save development time in Sayboard : https://github.com/Stypox/dicio-numbers
