add support for COPERNICUS/S2_SR_HARMONIZED to compute the tasseledCap components

[12rambau]

First of all thanks a lot for this package it's a hidden gem !

I am incorporating some of the functionalities within geetools as part of the refactoring process. Like eemont it's an exetention of GEE but we took a different angle, instead of extending directly the methods and class and blur the line between server and client side operations we decided to remain as much server-side as possible and we have hidden all the methods in a shared namespace "geetools".

In the test pipeline, I use a single image over the Vatican city or all the image-related test. it's coming from the COPERNICUS/S2_SR_HARMONIZED which is not supported for the tasseledCap method. Would it be possible to add it ?

Hey @12rambau!

The TC in this repo works actually with L1C, which can't be extended to L2A (SR), so for now it is not possible unless new coefs are published. Maybe @aazuspan knows best this! ;)
