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.

Blank

Blank()

Validates if the given input is a blank value (null, zeros, empty strings or empty arrays, recursively).

We recommend you to check Comparing empty values for more details.

v::blank()->assert(' ');
// Validation passes successfully

v::blank()->assert(0);
// Validation passes successfully

v::blank()->assert(false);
// Validation passes successfully

v::blank()->assert(['', ' ', '0.0', []]);
// Validation passes successfully

v::blank()->assert(new stdClass());
// Validation passes successfully

It's similar to Falsy, but way stricter.
