Improve modification constructor to work with values with non-default values as well

Currently, table->new() method takes all required values (which means those which have no default value). This leads to a problem that you can have e.g. five values related to user's name (2x degree, first name, middle name, last name; only first and last name are obligatory), but you have to split the whole group to two parts – obligatory and optional – which is not convenient:

$user = $this->usersTable->new($firstName, $lastName);
// ...
$user->modifyDegreeBefore($degreeBefore);
$user->modifyMiddleName($middleName);
$user->modifyDegreeAfter($degreeAfter);

We can make several things about it:

• let modification class, which is called in table's new() method, to have constructor with parameters as well – from()
• create two types of constructor – one for all fields and one for required only fields – from() & fromMandatory(); in the "all fields" constructor we can take advantage of PHP8's named arguments to pass optional fields if not needed (but we have to deal with default value detection first)
• use modifications directly and deprecate table's API (maybe not good idea?)

  $user = UserModification::from(firstName: $firstName, middleName: $middleName, lastName: $lastName);
