b10a7d0396 Added experimental support for Raspberry Pi devices
This commit adds support for the Raspberry Pi, which allows users to
create a completely standalone music visualization system. The Raspberry
Pi should be connected directly to a ws2812b LED strip. A PWM-capable
GPIO pin should be connected to the data line of the LED strip. A USB
audio input device should be connected to one of the Raspberry Pi's USB
ports.

It is recommended that the GUI and FPS output be disabled when running
the visualization on the Raspberry Pi. These features can degrade
performance on the already computationally limited Raspberry Pi.

4b6f9a807b Fixed bug where some FPS values raised exceptions
Fixed a bug where certain config.FPS values would result in arrays with
mismatched dimensions. The mismatched dimensions occurred because an
integer was rounded instead of truncated. This is now fixed and
exceptions should no longer be raised when certain FPS values are used.

46b404120f Fixed bug where ComboBox didn't match current effect
Fixed a bug where the GUI ComboBox value would sometimes not match the
effect being displayed. This bug sometimes occurs when the GUI is first
initialized. This change now ensures that the ComboBox value is
correctly initialized.

c725d395be Added ComboBox to GUI for effect selection
Added a ComboBox to the GUI to allow the user to change the
visualization effect without having to restart Python. The user can now
select from one of the following visualizations using the GUI: 'Scroll
effect', 'Spectrum effect', 'Energy effect'

0f5c05339c Fixed a byte encoding error that occurred in Python 3
Fixed an error that caused strange byte encoding in Python 3. This error
was caused by a mistake in porting code from Python 2.7 to Python 3 and
would cause strange LED flickering behaviour. The LED update code should
now work properly in Python 2.7 and Python 3.

f860922d67 Removed ws2812b i2s library dependency, updated README
I have added a pre-configured version of the ws2812b i2s library to the
Arduino code. This removes the need to download and install the ws2812b
i2s library manually. The ws2812b code has been preconfigured to reduce
the temporal compared to the default value. The default value was found
to cause excessive flickering. The readme has been updated to reflect
this change. Also added a note about the maximum number of LEDs (255)

27a0448203 Added LED strand test to LED.py
Added a test routine to led.py to do a simple LED strand test. The
strand test scrolls a red, green, and blue pixel across the LED strip
forever.

e874ed3b2c Resolved issues with Python 3.5 compatibility
Fixed some bugs that occurred in Python 3.5 but were not present in
Python 2.7. Most compatiblity issues were caused by incompatible type
casting of numpy arrays.
