LED Strip (sorry the branch name is still neopixel_strip)

Here is the pull request for the generic version from here

It's necessary per the protocol, but has no meaning for this particular device. For something like analog input or pwm it specifies the resolution in number of bits.

Please report which Arduino (and Arduino-compatible) devices you have tested this with.

Try to use it with other features such as analog input, pwm and digital outputs and an I2C device to be sure there are no unexpected issues in the case that a user has a LED, a couple of pots, a servo and an accelerometer (or other i2c device) attached simultaneously.

Also, please report approximately how much memory this code consumes (you can find out using the freeMemory function of the ArduinoUnit library by printing the memory pre and post initialization of your library, you can also report ongoing in a loop to see if there are leaks - although I'd assume Adafruit has done a pretty good job ensuring their library is stable).

Hey all. We've been having a chat today @rwaldron me & others) about
appropriate place to deal with the silliness that is the "almost spi"
protocol that is the ws2812 as it relates to both J5 and firmata and having
to deal with it on both sides.

I think we've come up with a more sustainable solution that will allow us
to deal with future cases of this exact scenario. This is more J5 specific
but I think it applies to firmata too.

I need to do a proof of concept hopefully over next couple of nights so
I'll report back what I find and feed it into you guys.

#168 (comment).

See #132 for an update on how we're thinking to include Firmata features that wrap 3rd party libraries.

I'm going to withdraw this proposal for now. This was original written to add support into Johnny-five, but Rick and a few others came up with a better solution (I2C interface for led strips), so I think this is no longer needed
