Change prefix from xrb to nano.

[damagicalcat]

it is called nanocurrency not raicurrency

For anyone who needs help changing from XRB to nano:
"nano".concat(address.slice(3))

This is already supported by the lib, notably using useNanoPrefix. It’s not the default for backwards compatibility reasons, but I might reconsider this for a new version.
