Add worker pool to the listener to prevent blocking. It is used only for
notary notifications and new block events handling since it uses RPC
calls. That may lead to the deadlock state: neo-go cannot send RPC until
notification channel is read but notification channel cannot be read since
neo-go client cannot send RPC.

Updated client now supports subscription to chain notifications and RPC
switch between provided RPC endpoints.

Provide current heights as an argument to ticker.
Zero height disables any checks, thus corresponding to the old
behaviour. If non-zero height is used, ignore the tick if the height
is less than the timer tick state.

After `Listen` has raw receiver and calls `listen` which has pointer
receiver, leading to ineffectual assign to `started` field.
Always use `listener` by pointer, to avoid similar bugs.

Provide explicit argument to `sendCommitteeTx` signifying whether a tx
should try to use group signer.

NEP-17 transfer method returns boolean value signifying if the operation
was successful. Fail the transaction if it was not.

When IR node configured without main chain, both
`morphListener` and `mainnetListener` are pointing
into single listener component. We should not call
`Stop()` twice, because it may trigger channel
closing in neo-go or other components and it
can throw panic.

Check the full file name instead of just prefix. Also, fix a bug where
a single missing wallet could lead to an incorrect size calculation.

Prevent attemts to connect to the failing endpoint multiple times.
This speeds up all invocations a bit and removes excessive error logs.

Also, remove optimization comments:
1. Having to maintain an execute the same logic for headers as for
objects is quite inefficient, as it increases memory footprint.
2. Unmarshaling object is a cheap operation if data slice is in memory.
3. For unmarshaling header-only, I think we need SDK support.

`Degraded` mode is set automatically after error counter is over the
threshold. `ReadOnly` mode can still be set by an administrator.

Add `WithEncryption` option that passes ECDSA key to the persistent session
storage. It uses 32 bytes from marshalled ECDSA key in ASN.1 DER from in
AES-256 algorithm encryption in Galois/Counter Mode.
