Allow checking versions constraints for arbitrary packages

This realease adds a new step that allows you to conditionally run tests, depending on whether a package satisfies particular version constraints. Constraint syntax is the same as those used by Composer:

  Scenario: Running when dependency is satisfied
    Given I have the "codeception/module-cli" package satisfying the "*"
    And I have the following code
      """
      atan("zz");
      """
    When I run Psalm
    Then I see these errors
      | Type                     | Message |
      | InvalidScalarArgument    | /./     |
    And I see no other errors

You can also check for the version of the module itself:

  Scenario: Running when dependency is satisfied
    Given I have the "weirdan/codeception-psalm-module" package satisfying the "^0.5 || ^0.6"
    And I have the following code
      """
      atan("zz");
      """
    When I run Psalm
    Then I see these errors
      | Type                     | Message |
      | InvalidScalarArgument    | /./     |
    And I see no other errors
