ssqueezepy v0.5.0

Synchrosqueezing arrives to Python:

• Continuous Wavelet Transform, forward & inverse, beating PyWavelets' & scipy's
• CWT-based synchrosqueezing, forward & inverse
• Wavelet visualizations
• Docs/comments explaining relevant concepts
• Several important fixes and performance optimizations relative to original MATLAB repository
• Greater flexibility and improved edge-case handling relative to latest MATLAB implementations

Planned for v0.6.0:

• Short-time Fourier Transform, forward & inverse
• STFT-based synchrosqueezing, forward & inverse
• Generalized Morse Wavelets

Existing users: please review code anew; too many changes to note between Prerelease 2 and v0.5.0. This changes onward, with every change explicitly tracked.
