Limit DAC Sample Rate

Tone sample length is now checked to make sure max DAC sample rate is not exceeded and adjusted as needed.

To use in CircuitPython, simply install the Adafruit CircuitPython bundle.

Tone and file playback fix!

Added deinit() to stop_tone and play_file to eliminate issues when using both in the same program.

To use in CircuitPython, simply include from adafruit_circuitplayground.express import cpx at the top of your file. The library is built into CircuitPython for Circuit Playground Express.

Reduce library size

Library size reduced by about 630 bytes when loaded into memory, about 12% smaller.

No functionality changes except that graceful error checking for CircuitPython versions before 2.2.0 has been removed. These versions will still fail, but less elegantly.

Thanks @kattni for testing and review!

3.0 compatibility updates!

Updates to start_tone and play_file to allow them to work with the changes to audioio made for 3.0. Backwards compatibility maintained for 2.x.

Update documentation

Merge pull request #30 from sommersoft/new_docs

Improve Ref Docs

Improved reference documentation.

Thanks to @sommersoft for the great work!

Added an examples folder and several example .py files.

Added the following files: acceleration.py, pixels.py, shake.py, tapdetect.py, tapdetectsimple.py, tone.py, and touched.py in the examples folder

Now with single and double tap options!

Tap detection is now configurable using cpx.detect_taps to determine whether to look for single or double-taps.

Improved documentation with examples for using detect_taps and tapped.

Designed to work with CircuitPython 2.2 or newer (currently available as 2.2rc1). This library will work with older versions of CircuitPython, although some functionality will not be available.

To use in CircuitPython, simply install the Adafruit CircuitPython bundle or the zip from here that matches the version of CircuitPython you are using.

Small fix

Small fix to make Express init on 2.1.0 when set_tap isn't available. Thanks to smolz on the forum for the report.

Now with double_tap!

Added double-tap capability with double_tap. It requires CircuitPython 2.2.0 (currently available as 2.2.l0rc1) or newer.

Thanks to @tannewt for helping!
