add new proxy types: set_root_weights #751
Description
Is your feature request related to a problem? Please describe.
I don't want to manually have to change my root weights every 1000 blocks according to https://vote.datura.ai/delegators-list. I want to automate it from a server that does this in a cron job, but I don't want to expose my coldkey on a remote server that I don't own.
Describe the solution you'd like
I would like to be able to create a proxy that can only set root weights, and not have permissions to do any other actions.
