Tasseled Cap Transformations

[aazuspan]

• Fix Tasseled Cap Transformations #5 by adding tasseledCap function to Spectral module for calculating brightness, greenness, and wetness from Sentinel-2, MODIS, and Landsat 4-8 images and image collections
• Add utility function for matching platforms to tasseled cap coefficients
• Update tests and docs to include tasseledCap

Let me know if any changes are needed :)

Wow! This was pretty fast, @aazuspan! 🚀 Awesome job!

Since the last time we had troubles with the online testing (in eemont), I will download and test the features in local and then I will merge the PR!

Thank you very much, @aazuspan!

Works perfectly! Amazing job, @aazuspan! I'm merging it now 🚀

If you want to add it to eemont, you can do it now :) ee_extra is already a dep, so you can just call ee_extra.Spectral.core.tasseledCap in the image.py and imagecollection.py modules to extend the ee classes!

Soon we will be releasing the next version of ee_extra! :)

Thanks @davemlz! I'll start adding this to eemont now.
