How to determine Validator stake weight.

With the launch of dTao, stakeholder may place stake on root or on a subnet.  In order to determine how much stake a validator has on a subnet, these values are combined.

Root stake is weighted at a lower value that the alpha stake.  The weighting parameter `tao_weight`  is defined on-chain (currently 0.18)

root\_stake: The amount of tao staked to a validator on root.\
tao\_weight : Defined on chain as 0.18.
alpha\_stake: The amount of alpha staked to a validator on the subnet
stake\_weight: The value used to determine emissions.

$$
stake_{total} = stake_{alpha} + stake_{root} \cdot tao_{weight}
$$
