elements: convenience methods for dealing with assets

We don't preserve detailed asset information at the moment, so provide a
way to convert from a sat to an amount_asset struct.

We also need a way to convert from an 'amount_asset' to a 'value' for
elements, which for explicit (i.e. non-blinded) asssets is a 0x01 prefix
plus the big-endian encoded value.
