Add support for newer versions of Mongoose (5.x.y)
Add support for newer versions of Mongoose (5.x.y)

mongoose-float works fine with the latest versions of Mongoose, but that
wasn't reflected in the module's dependencies. This caused npm to
complain about missing peer dependencies when installing mongoose-flat
with newer versions of Mongoose.

Now any Mongoose version between v4 and v5 is supported.
