Bruno BELANYI ffd6a20a30 transaction: add CSV deserialization
It is unfortunate that both [1] and [2] conspire to make this code way
worse than it could otherwise be with a saner (de)serialization format.

We both need to introduce `TransactionRecord` due to tagged enums not
being powerful enough in CSV, and make its `amount` field optional to
deal with the varying number of fields for each kind of transaction.

Represent each enum variant with its own type to allow stronger typing
when processing only a singular type of transactions.

Bruno BELANYI 1ea0505098 cargo: move 'processor' to 'bin' directory
I like to keep executables in their own folders, and the as much of the
business logic in a library at the root.

Bruno BELANYI c17a70bb39 cargo: add 'fpdec' dependency
Instead of implementing custom fixed-point decimal numbers, let's make
use of an existing implementation until it is deemed inappropriate.
