[ol types] Error types in rust for known 0L errors

[0o-de-lally]

Create a list of known errors which 0L code throws from the MoveVM on transaction failures. This would allow us to create better messages and control flow for client tools like tower, carpe, and txs.

Here's where txs defines a transaction error.

We would need an Enum of OLErrors, which would have several variants: TowerUpperBound, TowerWrongOrder, etc. which will map to an error number on Move side.
