##### `getversion`
NeoGo can return additional fields in the `protocol` object depending on the
extensions enabled. Specifically that's `p2psigextensions` and
`staterootinheader` booleans and `committeehistory` and `validatorshistory`
objects (that are effectively maps from stringified integers to other
integers. These fields are only returned when corresponding settings are
enabled in the server's protocol configuration.
##### `getnep11transfers` and `getnep17transfers`
`transfernotifyindex` is not tracked by NeoGo, thus this field is always zero.

Package actor provides a way to change chain state via RPC client.
This layer builds on top of the basic RPC client and simplifies creating,

state is changed). It's generic enough to be used for any contract that you may
want to invoke and contract-specific functions can build on top of it.
