{- | A type-level function that maps a Michelson type to its Tezos RPC representation.
For example, when we retrieve a contract's storage using the Tezos RPC,
all its @big_map@s will be replaced by @nat@, representing a big_map ID.
>>> :k! TAsRPC ('TBigMap 'TInt 'TString)
...
= 'TNat
>>> :k! TAsRPC ('TList ('TBigMap 'TInt 'TString))
...
= 'TList 'TNat
>>> :k! TAsRPC ('TPair 'TString ('TPair 'TAddress ('TBigMap 'TInt 'TString)))
...
= 'TPair 'TString ('TPair 'TAddress 'TNat)
NB: As far as we are aware, details of RPC representation of Michelson
types are not documented. We know empirically that @big_map@s are
represented as their ids, and are the only type with an explicitly
different representation.
Whether @TAsRPC@ needs to propagate into type parameters then depends on
whether a value can hold big_map values.
* Values of type @option a@, @list a@, @pair a b@, and @or a b@ can
contain big_map values, so their RPC representations are @option (TAsRPC a)@,
@list (TAsRPC a)@, @pair (TAsRPC a) (TAsRPC b)@ and @or (TAsRPC a) (TAsRPC b)@.
* The keys of a @map k v@ cannot be big_maps, but the values can, so its
RPC representation is @map k (TAsRPC v)@.
* Values of type @set a@ cannot contain big_maps, so its RPC
representation is just @set a@.
* Values of type @contract a@ cannot contain big_maps either, because
it's just a wrapper for an address and an entrypoint name, so its RPC
representation is just @contract a@. The same reasoning applies to
@ticket a@ and @lambda a b@.

{- | A type-level function that maps a type to its Tezos RPC representation.
For example, when we retrieve a contract's storage using the Tezos RPC, all its 'BigMap's will be replaced
by 'BigMapId's.
So if a contract has a storage of type @T@, when we call the Tezos RPC
to retrieve it, we must deserialize the micheline expression to the type @AsRPC T@.
> AsRPC (BigMap Integer MText) ~ BigMapId Integer MText
> AsRPC [BigMap Integer MText] ~ [BigMapId Integer MText]
> AsRPC (MText, (Address, BigMap Integer MText)) ~ (MText, (Address, BigMapId Integer MText))
The following law must hold:
> TAsRPC (ToT t) ~ ToT (AsRPC t)
In other words, `ToT` and `AsRPC`/`TAsRPC` must be commutative.

> annOptions = annOptions @ExampleStorage
Note that if the type doesn't contain type variables or only contains phantom
type variables, 'HasRPCRepr' constraint is omitted, as it would be redundant.
@HasAnnotation@ and its methods must be in scope.
When 'droRecursive' is @True@, recursively enumerate @data@, @newtype@ and
@type@ declarations, and derive an RPC representation for each type that doesn't
yet have one.
You can also pass in a list of types for which you _don't_ want
an RPC representation to be derived in 'droRecursiveSkipTypes'.
In this example, this will generate an RPC representation for @A@ and @B@, but
not for @C@ (because we explicitly said we don't want one) or @D@ (because it
already has one).
