This adds the first version of the fees package, responsible for performing fee estimation of network transactions. The main goal of fee estimation is to allow the usage of dynamic fees by wallets, contingent on block contention and the desired confirmation range for a given transaction. This version was based on bitcoin core fee estimation.
