Incompatible PHP requirements

[kenorb]

When installing underscore-php v2.0.0, it reports that it requires php: >=5.4.0 in its composer.json, however at the same time it requires doctrine/inflector (^1.0) which installs v1.3.0 and it requires PHP ^7.1.

Test on empty folder:

$ composer require anahkiasen/underscore-php:2.0.0
$ find vendor -name \*.php -exec php56 -l {} ';'
