Crate audio_processor_testing_helpers

Provides helpers for testing audio processors.

• Drawing charts from a vector with plotters - charts
• Getting asset paths relative to the crate being tested - relative_path!
• Comparing floats - assert_f_eq
• Calculating RMS - rms_level
• Generating sine buffers - sine_buffer
• Generating frequency response charts - charts
