3.6.0.0

@parsonsmatt
- #422
  - The instance of HasField for SqlExpr (Maybe (Entity a)) joins Maybe values together. This means that if you leftJoin a table with a Maybe column, the result will be a SqlExpr (Value (Maybe typ)), instead of SqlExpr (Value (Maybe (Maybe typ))).
  - To make this a less breaking change, joinV has been given a similar behavior. If the input type to joinV is Maybe (Maybe typ), then the result becomes Maybe typ. If the input type is Maybe typ, then the output is also Maybe typ. The joinV' function is given as an alternative with monomorphic behavior.
  - The just function is also modified to avoid nesting Maybe. Likewise, just' is provided to give monomorphic behavior.
  - subSelect, max_, min_, and coalesce were all given Nullable output types as well. This should help to reduce the incidence of nested Maybe.
  - The operator ??. was introduced which can do nested Maybe. You may want this if you have type inference issues with ?. combining Maybe.
- #420
  - Add a fixity declaration to ?.
- #412
  - The random_ and rand functions (deprecated in 2.6.0) have been removed. Please refer to the database specific ones (ie Database.Esqueleto.PostgreSQL etc)
  - The sub_select function (deprecated in 3.2.0) has been removed. Please use the safer variants like subSelect, subSelectMaybe, etc.
  - The ToAliasT and ToAliasReferenceT types has been removed after having been deprecated in 3.4.0.1.
  - The Union type (deprecated in 3.4) was removed. Please use union_ instead.
  - The UnionAll type (deprecated in 3.4) was removed. Please use unionAll_ instead.
  - The Except type (deprecated in 3.4) was removed. Please use except_ instead.
  - The Intersect type (deprecated in 3.4) was removed. Please use intersect_ instead.
  - The SubQuery type (deprecated in 3.4) was removed. You do not need to tag subqueries to use them in from clauses.
  - The SelectQuery type (deprecated in 3.4) was removed. You do not need to tag SqlQuery values with SelectQuery.
- #287
  - Deprecate distinctOn and distinctOnOrderBy. Use the variants defined in PostgreSQL module instead. The signature has changed, but the refactor is straightforward:
```
    -- old:
    p <- from $ table
    distinctOn [don x] $ do
        pure p

    -- new:
    p <- from $ table
    distinctOn [don x]
    pure p
```
- #301
  - Postgresql upsert and upsertBy now require a NonEmpty list of updates. If you want to provide an empty list of updates, you'll need to use upsertMaybe and upsertMaybeBe instead. Postgres does not return rows from the database if no updates are performed.
- #413
  - The ability to coerce SqlExpr was removed. Instead, use veryUnsafeCoerceSqlExpr. See the documentation on veryUnsafeCoerceSqlExpr for safe use example.
  - unsafeCeorceSqlExpr is provided as an option when the underlying Haskell types are coercible. This is still unsafe, as different PersistFieldSql instances may be at play.
- #420
  - The LockingKind constructors are deprecated, and will be removed from non-Internal modules in a future release. Smart constructors replace them, and you may need to import them from a different database-specific module.
- #425
  - fromBaseId is introduced as the inverse of toBaseId.
  - toBaseIdMaybe and fromBaseIdMaybe are introduced.

- #376
  - When using Postgres 15, LIMIT, and the locking functions, you could accidentally construct SQL code like:
    
    ... LIMIT 1FOR UPDATE ...
    
    This parsed on Postgres <15, but the new Postgres parser is more strict, and fails to parse. This PR introduces newlines between each query chunk, which fixes the issue.

3.3.4.0

@parsonsmatt
- #205
  - More documentation on the Experimental module
  - Database.Esqueleto.Experimental now reexports Database.Esqueleto, so the new "approved" import syntax is less verbose. Before, you'd write:
```
import Database.Esqueleto hiding (from, on)
import Database.Esqueleto.Experimental
```
    Now you can merely write:
```
import Database.Esqueleto.Experimental
```
    Users will get 'redundant import' warnings if they followed the original syntax, the solution is evident from the error message provided.
