Request to add drought indices in eemont

[pkpnerist]

** Feature Request for eemont or ee extra**
Hello Dr David Congratulations for nice contribution to making easy use of GEE. I request to add in your eemont package few mode drought indices. I did not find way to fit distribution in GEE or in GGE related packages in python.

I request to add some more indices like standardized precipitation index(SPI).
The SPI calculation for any location is based on the long-term precipitation record for a desired period. This long-term record is fitted to a probability distribution, which is then transformed into a normal distribution so that the mean SPI for the location and desired period is zero (Edwards and McKee, 1997). Please find link of different drought indices https://www.droughtmanagement.info/indices/.
Thanks
