* chore_: unused `BuildTx` function removed from the processor interface and types that are implement it
Since the `BuildTx` function is not used anywhere, it's removed from the code.
* fix_: resolving nonce improvements
When the app sends more than a single tx from the same account on the same chain, some
chains do not return appropriate nonce (they do not consider pending txs), because of
that we place more tx with the same nonce, where all but the first one fail.
Changes in this PR keep track of nonces being used in the same sending/bridging flow, which means
for the first tx from the multi txs the app asks the chain for the nonce, and every next nonce is resolved
by incrementing the last used nonce by 1.
* 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
