Fix SPDX headers in all files
I ran the `bin/console spdx --fix` with different strategies for
different files. For most of the core classes, since they've been
drastically rebuilt, I've run it with the `git-blame` strategy, for for
the `src/Validators`, in which the API changed completely but the logic
remains the same, I use the `git-log` strategy.

# Base
- `Base(int $base)`
- `Base(int $base, string $chars)`
Validate numbers in any base, even with non regular bases.
```php
v::base(2)->assert('011010001');
// Validation passes successfully
v::base(3)->assert('0120122001');
// Validation passes successfully
v::base(8)->assert('01234567520');
// Validation passes successfully
v::base(16)->assert('012a34f5675c20d');
// Validation passes successfully
v::base(2)->assert('0120122001');
// → "0120122001" must be a number in base 2
```
