xactmon: Deploy xactmon

`xactmon` is a new tool I developed to parse transaction notifications
from banks and automatically import them into my personal finance
tracker.  It is designed in a modular fashion, composed of three main
components:

* Receiver
* Processor
* Importer

Components communicate with one another using an AMQP exchange.
Hypothetically, there could be multipel implementations of the receiver
and importer components.  Right now, there is only a JMAP receiver,
which fetches email messages (from Fastmail), and a Firefly III
importer.  The processor is a singleton, handling notifications from the
receiver, parsing them into a normalized format, and passing them on to
the importer.  It uses a set of rules to decide how to parse the
messages, and supports using either a regular expression with named
capture groups or an Awk script to extract the relevant information.
