* emulator: block::Transaction -> block::transaction::Transaction

* Refactor

* emulator: Fix bug

* emulator: Support for emulator-extern

* emulator: Refactor

* Return vm log and vm exit code.

* fix build on macos, emulator_static added

* adjust documentation

* tvm emulator, run get method

* Added more params for transaction emulator

* Added setters for optional transaction emulator params, moved libs to a new setter

* Added actions cell output to transaction emulator

* fix tonlib build

* refactoring, rand seed as hex size 64, tvm emulator send message

* tvm send message, small refactoring

* fix config decoding, rename

* improve documentation

* macos export symbols

* Added run_get_method to transaction emulator emscipten wrapper

* Fixed empty action list serialization
