essentially completely reorganised the project.
previous contents of the dsa folder have now been split into emulator/ tooling/ and libraries/
libraries is for common functionality across crates, tooling is for core binaries needed for building and debugging DSA projects, including dsx client/server/build
emulator contains the dsa_emulator crate that implements the core DSA emulator, the dsa_gui crate that implements the graphical user interface for the emulator & all future tooling under a unified application, and finally the dsa_cli crate which will eventually provide lightweight wrapper for the core emulator, simply providing a tool for running DSA binaries without the overhead of a heavy GUI.
