Add a wavelet-domain functionality #133

BLIP currently operates on a series of short Fourier transforms. The GLASS global fit operates in the wavelet domain; see https://arxiv.org/abs/2009.00043. To ready BLIP for Global Fit integration, we should be able to do wavelet domain analyses as well. Steps:

  1. Research the LISA wavelet-domain response functions
  2. Add code to calculate these response functions
  3. Research the wavelet-domain likelihood
  4. Implement the wavelet-domain likelihood
  5. Test and compare SGWB analyses for short Fourier transforms vs. the new wavelet domain analyses
