Compact output

[ssfrr]

With this PR the default test output looks like (you'll have to imagine the colors):

Array playback
4 facts verified.

AudioNode Stopping
1 fact verified.

WAV file write/read
3 facts verified.

Audio Device Listing
1 fact verified.

Validating TestNode allocation
1 fact verified.

AudioMixer
Failure :: (line:40) :: 1 Input Mixer :: got 42
42 => 43

Out of 9 total facts:
  Verified: 8
  Failed:   1
  Errored:  0

SinOSC
7 facts verified.

ArrayPlayer
5 facts verified.

Gain
1 fact verified.

LinRamp
3 facts verified.

And the compact output looks like:

Array playback: ....
AudioNode Stopping: .
WAV file write/read: ....
Validating TestNode allocation: .
AudioMixer: ...F.....
Failure :: (line:40) :: got 42
42 => 43

SinOSC: .......
ArrayPlayer: .....
Gain: .
LinRamp: ...

The individual test output characters are printed as the tests run, with any failed tests being printed after each facts block.

I'm going to try to put this in, probably manually
