* fix_: filtering out routes which do not match the amount in
* fix_: finding the best route logic updated
* fix_: "to" chains being used in sending bridge tx via hop are more explicit
Using `ChainIDTo` depicts better an intention which chain should be used.
* chore_: checking for required balance improved
An error contains now more details, for which token on which chain there is not enough balance for
executing a tx. Also check for required balance now calculates in fees for all tx that possibly can be
sent from the same chain.
- router logic splitted into two more logical functions
- locked amount validation improved
- hop and swap processors cached data kept per from/to chain and from/to token
- Clear function which clears the local cache is added
- process of evaluating `amountToSend` if more than a single network is locked is improved
- optimized params for require approval function
