Add reify and unreify to Table class
...
Previously these were implemented with `unsafeCoerce`, which was mostly correct, but was incorrect for certain instances of `HList`. With this change, `deriving Rel8able` will now fail to type check in those instances.

Add instances for 6 and 7 tuples (after all, they're free now)
...
We stop at 7 though because even GHC doesn't provide Generic instances for 8-tuples and beyond.

Add better generic deriving for EqTable, OrdTable and ToExprs
...
This builds upon the `Rel8.Generic.Record` machinery introduced in the previous commit. It means that we can use generic implementations of the `Table`, `EqTable`, `OrdTable` and `ToExprs` for all tuple types, rendering `HPair`, `HTrio`, `HQuartet` and `HQuintet` unnecessary (this commit removes them).

Allow generic deriving of Table instances for non-record types
...
The is implemented using new machinery in `Rel8.Generic.Record`, which transforms the generic representation of any type to be as if that type was a record. Numeric labels are assigned to anonymous field selectors like `_1`, `_2`, `_3` and so on.

Make Rel8able have kind ((X -> Type) -> Type) -> Constraint
...
Previous it was `((Type -> Type) -> Type) -> Constraint`. The problem is this clashes with things like `HKD` from `higgledy`. We can use GADTs and PolyKinds hacks to get around this while mostly retaining the same API. The only major difference is we use `Result` in places where we used `Identity` before.

Simplify Column type family
...
Now that the Field type family only needs a Necessity and a Type, we don't need to "parse" the Type to find the Necessity, we can instead just make it so that Column creates a Required field, and repurpose the name Default to be a type family that creates an Optional field.
The previous "parsing" approach was brittle sometimes, particularly in the case of polymorphism.
