Integrated Argon2 algo chukwa (TRTL) and wrkz (#258)
* Integrated embedded config parsing #245

* cleanup

* Cleanup in remotelog

* Fixed MS Visual Studio 2019 compatibility

* Embedded config parsing only for miner not server

* wip

* Finished delete template

* WIP

* Integrated Argon2id/chukwa algo

* Added chukwa-wrkz algo variant

* Cleanup argon2-512 (chukwa/trtl) and argon2-256 (wrkz) parsing

* WIP other argon2 coins

* Cleanup and donate fix
