keys: add simple LRU key cache for 1024 elements
...
The cost of Y calculation from X is comparable with signature check, so it
reduces witness check overhead by ~30% for cached keys and gives ~5% overall
boost in TPS.

crypto/consensus: sign hashes and cache them for consensus payloads
...
Avoid serializing payload again and again for various purposes. To sign it, we
only need a hash.
Some 2.4% gain in TPS could be achieved with this.

particular EC point. ecdsa.PublicKey has this information.

keys: make NEP2Decrypt return a PrivateKey rather than WIF
...
There is no point in encoding the output of this function in a WIF format,
most of the users actually want the real key and those who need a WIF can
easily get if from the key (and it's simpler than getting the key from the
WIF).
It also fixes a severe bug in NEP2Decrypt, base58 decoding errors were not
processed correctly.

io: add type-specific read/write methods

This seriously improves the serialization/deserialization performance for
several reasons:
* no time spent in `binary` reflection
* no memory allocations being made on every read/write
* uses fast ReadBytes everywhere it's appropriate
It also makes Fixed8 Serializable just for convenience.
