Added util function getSovereignAccountAddresses

[ekenigs]

Description

Basically, I implemented what we have here https://docs.moonbeam.network/builders/interoperability/xcm/xc-registration/xc-integration/ but without using api. The script itself is here: https://github.com/Moonsong-Labs/xcm-tools/blob/main/scripts/calculate-sovereign-account.ts.
