Grégoire Henry fc53f3b233 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)
```
