* `VerifyingKey.precompute()` supports `lazy` argument to delay
precomputation to the first time the key is used to verify a signature.
* Make created signatures correct when the hash used is bigger than the curve
order bit size and the curve order is not a multiple of 8
* Speed up library load time by calculating the generator point multiplication
tables the first time the points are used, not when they are initialised.

* Support for reading and writing private keys in PKCS#8 format.
* `to_pem` and `to_der` now accept new parameter, `format`, to specify
* the format of the encoded files, either the dafault, legacy "ssleay", or
* the new `pkcs8` to use PKCS#8. Note that only unencrypted PKCS#8 files are
* supported.
* Add `allow_truncate` to `verify` in `VerifyingKey`, it defaults to True,
* when specified as False, use of large hashes smaller than curves will be
* disallowed (as it was in 0.14.1 and earlier).
* Correctly calculate signatures for private keys equal to n-1.
* Make `PointJacobi` and thus `SigningKey` and `VerifyingKey` pickleable.
