Problem
obtaining the minimum value for rent exception is most commonly obtained from the
getMinimumBalanceForRentExemption
rpc method, which results in a network call and therefore slowerSummary of Changes
add a sync
getMinimumBalanceForRentExemption
function to perform the math required to calculate the min rent exempt valueNote: there is a trade off here we are making in that IF/WHEN the min rent value is changed or made dynamic, this calculation would become invalid. This should be acceptable for the foreseeable future since this type of change would require a SIMD and have a long rollout time, allowing ample time to adjust this function
