Rename marshal -> toBytes, unmarshal -> fromBytes
...
For two reasons:
- to distinguish them from the marshalling functions
from constantine
- they do not follow the convention that something
that is marshalled can be unmarshalled, because
they take in 31 bytes but produce 32 bytes

Only support unmarshalling of little-endian bytes
...
Big-endian bytes had weird padding; 0's to the right,
then a single 0 to the left.

move unmarshal into its own module called 'io'

Includes separate tests for unmarshalling that
were previously tested as part of the merkleRoot
calculation.

and big endian byte arrays.
