fix #89 with Image component v2.0 + 23 tests (#90)

* qtbot is needed in any test that uses a QObject
previously these tests would fail if they ran before qtbot was initialized by another test. I'm now running tests in a random order

* add tests for drawBars, readAudioFile, BlankFrame

* replace numpy.seterr with numpy.errstate

* fix incorrect comment

* add MockVideoWorker and imageDataSum

* test further into visualization (less likely to be a false positive)

* test FloodFrame function

* add failing test for Image component
one step towards fixing #89

* test component name CLI parsing

* prevent log warning when 1 setting changed

* correct tests to use widgets when needed

* test undo and blockSignals

* remove stretch_scale (use scale only)

* image ignores scale if stretch checkbox checked
fixes #89

* test Title Text component, ffmpeg command

* Image v2: replace stretched setting with resizeMode
3 resize modes are scale, cover, and stretch. Scale only applies when resizeMode is set to scale. Cover uses ImageOps.fit() to stretch while maintaining aspect ratio. Also, spinBox_scale was moved to be underneath comboBox_resizeMode.

* change transformData into staticmethod
the purpose is to allow easier reuse in other components

* add respondToAudio option to Image component
this causes the image to scale up and down slightly based on the input audio file

* cache static portion of image when animating
increases rendering speed of a 1-minute video by 12 seconds (based on two manual tests anyway)
