Retain a small part (6 or 9 bytes) of each chunk in memory for providing
the next iteration with enough context for finding the start/end marker

Set up generally useful stuff:
* chai.should()
* logger stubs
* globals in SandboxedModule, including Buffer and process, which are
now required in Node 12
The previous regex could mistake user provided pdf files, like
`fake_output.pdf`, as the final output file.
The frontend expects to find a `output.pdf` file on success.
When we mount the container's root filesystem as read-only, mount
an anonymous volume in /home/tex so that it's writable. Our TeX Live
images have cached content in /home/tex. This content will automatically
get copied by Docker into this anonymous volume.
- move setting into clsi.docker namespace
- rename the variable for images to allowedImages / ALLOWED_IMAGES
- add an additional check for the image name into the DockerRunner

The docker api returns each name with a `/` prefix.
In order to not interfere with pending compiles, the deletion process
has to acquire an internal lock on the container. The LockManager uses
the plain container name without the slash: `project-xxx`.
