   Refactor the sample crate into a modular collection of crates under dasp.

   • Refactor the sample crate into a modular collection of crates under dasp.
   • Rename repository from sample to dasp, where dasp stands for digital audio signal processing.
   • Add a suite of useful feature gates:
     • Add std to all crates. Can be disabled in order to use no_std.
     • Add a all-features-no-std feature to dasp, dasp_envelope, dasp_interpolate, dasp_signal, dasp_slice and dasp_window. Enables all features within a no_std context.
     • dasp_envelope crate:
       • peak - enables peak detector implementation.
       • rms - enables RMS detector implementation.
     • dasp_interpolate crate:
       • floor - enables Floor Interpolate implementation.
       • linear - enables Linear Interpolate implementation.
       • sinc - enables Sinc Interpolate implementation.
     • dasp_signal crate:
       • boxed - enables Signal implementation for Box<dyn Signal>.
       • bus - enables SignalBus trait.
       • envelope - enables SignalEnvelope trait.
       • rms - enables SignalRms trait.
       • window - enables signal::window module.
       • window-hanning - enables hanning window constructor.
       • window-rectangle - enables rectangle window constructor.
     • dasp_slice crate:
       • boxed - enables conversions between boxed slices.
     • The dasp crate has a feature for each of the above.
   • Make Window trait generic over its phase and amplitude type. Update the dasp_signal::window module items accordingly.
   • Remove unsafe uninitialized ring buffer constructors.
   • Remove equilibrium() and identity() constructors from Sample and Frame traitsin favour of EQUILIBRIUM and IDENTITY associated consts.
   • Remove Frame::n_channels function in favour of Frame::CHANNELS associated const.
   • Add implementation of Frame for all primitive Sample types where each are assumed to represent a frame of a monophonic signal. This greatly simplifies working with monophonic signal sources as demonstrated in the updated dasp_signal crate.
