[dudo50]

Include function that checks if ED on destination chain will be met for certain asset.

verifyExistentialDepositOnDestination(tx) //verifies whether ED will be met once the call is sent

Should check for balance of certain token and use formula if balance+xcm_amount-ED > 0 = returns true, balance+xcm_amount-ED<0 = returns false
