which means that we don't want to display to a user details of how much they have and how much is needed for fees, cause those data are very often
misleading, referring mostly to "how much user has".
New error added in case there is no positive balances across all enabled chains.
- 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
- handling `null` values in the Hop response
- using data returned from the Hop api when preparing data for estimation and calling `swapAndSend` and `sendToL2`
- estimating gas for bridges implemented in the bridges implementation types, avoiding wrong gas for placing bridge transactions
