possibly add #include <stdint.h> to number.h

[ghbyrkit]

when compiling for some, such as STM32, boards, I get errors of undefined 'uint32_t' and 'uint16_t'.

I believe that this can be resolved by adding '#include <stdint.h>' just after then multiple include safeguard, say at line 34.

If you have an alternative suggestion, I'm all ears!
This is using the IDE 2.2.1
