Use the existing Bisq API CLI utils for making calls to the daemon,
and formatting responses.
When/if the CLI is released on jitpack, this code can be removed
from this repo, and loaded from a gradle dependency.
This might give Python devs an easier time than if all the sample
code lived deep inside a gradle project. This means there is
no root project gradle build file; the reference-doc-builder and
java-examples modules are separate java projects, with their own
build files.
