Hey! Hey! Can u rel8?

This means that users defining new `DBType`s will have to additionally derive `Encodable` (but a simple `deriving Encodable` will suffice).
It also opens up the possibility of users defining non-`DBType`s that are `lit`able (and `select`able). For example, the `HKDT` helper makes allows arbitrary products of `DBType`s to be `lit`ed via `higgled`'s `HKD`:
```haskell
data S3Object = S3Object
{ bucketName :: Text
, objectKey :: Text
}
deriving stock Generic
deriving Encodable via HKDT S3Object
```
With the above loaded into GHCi:
```
>>> :t lit (S3Object mempty mempty)
lit (S3Object mempty mempty)
:: HKD S3Object Expr
```
The implementation is extensible, allowing for the possibility of other "strategies" (in addition to `DBType` and `HKD`) in the future.

Welcome!
Welcome to Rel8! Rel8 is a Haskell library for interacting with PostgreSQL databases, built on top of the fantastic Opaleye library.
The main objectives of Rel8 are:
-
Conciseness: Users using Rel8 should not need to write boiler-plate code. By using expressive types, we can provide sufficient information for the compiler to infer code whenever possible.
-
Inferrable: Despite using a lot of type level magic, Rel8 aims to have excellent and predictable type inference.
-
Familiar: writing Rel8 queries should feel like normal Haskell programming.
For more details, check out the official documentation.
