Moving all Client public API types to separate mod & binary serialization codegen for that mod (#1051)

* transaction moved

* trash remove

* ids move

* receipt

* tree-route

* blockchain info

* log_entry move

* trace filter moved

* executed & trace moved

* localized trace moved

* block status moved

* build scripts and codegen refs

* Cargo.lock update

* binary for blockstatus, blockchaininfo

* binary for trace

* trace filters binary ser

* binary for log entries & executed

* binary for receipt

* special case for u8 & transaction binary attribute

* resolved remaining issues & error binary serialization

* json-tests util import

* fix warnings

* ids attr

* add missing attributes

* Update build.rs
