New sniff to enforce tag order in docblocks

[fredden]

As mentioned here: PHPCompatibility/PHPCompatibility#1586 (comment)
The convention is for @dataProvider tags to be before @param tags and after the description. This can and should be enforced with a sniff.

As per PHPCompatibility/PHPCompatibility#1586 (comment) :

There are no good sniffs available to enforce this at the moment. Once I have some more time again, it's on my never-ending to do list to write better docs sniffs and make those available via PHPCSExtra.
