* Optimize `decode_len`

Instead of reading the full storage value into the runtime, we only read
at maximum `5bytes` from the storage into the runtime. Furthermore this
drops any handling with regards to set default values in
`decl_storage!`. If the value does not exists or the decoding of the
length fails, it will return `None`. To prevent people from messing
stuff up, this feature relies on the `StorageDecodeLength` trait that is
sealed by `frame-support` (aka only implementable inside this crate).

* Make `Digest` support `StorageAppend`

This adds support for `StorageAppend` to `Digest`. Digest is just a
wrapper around a `Vec` and we abuse the fact that SCALE does not puts
any special marker into the encoding for structs. So, we can just append
to the encoded Digest. A test is added that ensures, if the `Digest`
format ever changes, we remove this optimization.
