deprecate the ISO build functionality, we made it into grml
We simply stop building our own ISOs now. We can rely on the daily
grml builds or otherwise people can just `apt install` stressant on
their favorite Linux distribution.
Closes: #1

fix job file argument so it supports jobs with filename=
The sample job has a filename= argument which confuses fio: that
argument cannot be overriden from the commandline, contrary to what I
first believed. Even with the --filename argument on the commandline,
fio would fail:
root@rescue ~ # fio /usr/share/doc/fio/examples/basic-verify.fio --filename=/dev/sda --size=1000M --runtime=10s

The solution is not pretty, but it works: we create a tmpfile for the
job and rewrite the provided job to remove the filename= argument.
Alternatively, we could have just stop accepting the filename and
directory argument and assume the user will do the right thing with
the job provided, but I want defaults to work correctly.

fix unicode decode error in Python 3.7
The fio command call would completely fail with:
Traceback (most recent call last):
File "./stressant", line 448, in <module>
main()
File "./stressant", line 436, in main
testDrive(**vars(args))
File "./stressant", line 356, in testDrive
tmpfile.file.write(newjob)
TypeError: a bytes-like object is required, not 'str'
we were reopening the tmpfile here instead of using the fd anyways, so
it's better to use the higher level NamedTemporaryFile construct
instead.
This now works in Python 3.7 but hasn't beeen backwards-tested.

merge the two disk sizes arguments
There is no reason to keep those distinct when we send them all to fio
the same way in the end anyways.

do not verify disk wipes and use the "random" method
The former is because we don't want to waste time re-reading the
entire disk. The latter is because we don't want to trust governmental
entities (US DoD by default but other options include Canada federal
police, the RCMP) with our data.
