Make honest Aeson Eq instance

[bladyjoker]

I'm having tests that rely on semantical equality of Json objects, however I'm having issues with Aeson

Seems like upon reading into Aeons we the BigInt stringified as 1e+17 and then when writing to Aeson we get 100000000000000000.

Since Aeson implements the Eq instance using a stringified form of Json, for semantically the same Json objects we get 2 different textual representations (see above). Let's rather make this right and implement a proper equality instance that captures the semantics of what it means for 2 Json objects to be the same.
