Before all transactions were processed and when the failure was
simulated a message was printed and all the transactions still
processed. Now the store returns an error when the failure is simulated
which the listener expects so that it can gracefully shutdown the system
and close the context. The context must be closed correctly or the
checkpointer won't save the last processed transactionId to the file
system.

Every struct was put in its own file. Every method which is not used
outside the parser package was given package scope. All interfaces were
removed, they are implemented by the structs which are now used
everywhere needed as return values. There is no clear benefit of using
interfaces in this sample.

Created packages for the flat file store and the processor and moved
functions, variables and constants from listener.go to those packages.
Encapsulated everything not used outside the packages, introduced
model.go files which later might be extracted into a model package and
renamed parser/parsedBlock.go to parser/block.go.
