Starting from the processor.Block.Process all methods now return errors
if something goes wrong with unpacking of the blocks and reading the
transactions. In each function where the error is being propagated back
to client it is wrapped in a message with the function name. This makes
it easier to track down the error and see the propagation chain. Finally
the error is logged to the terminal and the go routine shuts down
gracefully. The graceful shutdown executes all deferred functions which
close the context, the checkpointer and the gateway.
Before panics were used everywhere which was an issue because the
unpacking of the blocks happened in a go routine. When a panic happens
in a go routine only the deferred functions of the go routine are called
but not those of the client which lead to unexpected behavior.
The transact function is also executed in a go routine therefore the
same typo of error handling was implemented there.

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.

Created parser, contract and utils packages and extracted each piece of
functionality into its own files. Removed "Get" prefix from methods and
changed return values from interfaces to structs.
