Switch to Base58.
...
Base48 was fun but... hell yeah... let's stay standard.
Public encoding of hash:
```
Block: "B..." (len: 51)
Operation: "o..." (len: 51)
Protocol: "P..." (len: 51)
Ed25519: "tz1.." (len: 36)
Contract: "TZ1.." (len: 36)
NetworkdId: "id.." (len: 30)
```
Other internal prefixes (in the RPC):
```
Hash of Michelson's expression: "expr..." (len: 54)
Ed25519 public key: "edpk..." (len: 54)
Ed25519 secret key: "edsk..." (len: 98)
Ed25519 signature: "edsig.." (len: 99)
Hash of a random seed nonce: "nce...." (len: 53)
Random seed: "rng...." (len: 53)
```

... until we properly store the nonce in the configuration file,
together with the expected difficulty.

use 256 bit target for proof of work
...
* SHA256 produces 256 bits pseudo-randomly uniformly, so you may
compare to a 256 bit target to get a proof of work
* If you pretend that the hash and targets are both integers between 0
and 2^256 - 1, then the target partitions the range into passing and
failing segments.
* In order to match the use of the `get_uint16` function from
`ocplib-endian`, the easiest way to encode `target` is as a `int list`
which works if not ideal
* This seems like the same thing bitcoin does; difficulty there is
actually not a primary notion but is calculated from a 256 bit target,
which is what gets adjusted over time
