* Test only on supported PHP versions on Travis CI.
* Preload OLE.php as contains important constants.
Were getting: Use of undefined constant OLE_PPS_TYPE_FILE - assumed 'OLE_PPS_TYPE_FILE' (this will throw an Error in a future version of PHP) in OLE/PPS/File.php:60
* Forbid installing on PHP 7.3 for time being.
pear/OLE does not really work on PHP 7.3, so this package is also unusable there.
