feat: check overflow

[Cyrix126]

That's a suggestion for how to handle operations that would overflow u64. If an overflow occurs, algorithms will returns an error.

To avoid having a lot of .checked_add(value).ok_or_else(||SelectionError::AbnormalHighValure)? repeated over the code, which can be a bit hard to read, a simple function sum reside in src/utils.rs

Another way would be to check at select_coin if the values given in inputs and options are abnormal. But then the overflows would still occur if the different algorithms are used directly.
