 Here's a command to test on a malformed VCD:
 `cargo run --release test-vcd-files/VCD_file_with_errors.vcd`

 # TODO
 
 ## Features
+ - [ ] macro for getting line number when propagating errors
  - [ ] re-order all signal timelines as binary balanced trees with respect to timestamps
        - support multithreaded re-ordering
+ - [ ] looks into making a macro for filename and linenumber later
  - [ ] Print out git commit or release number.
  - [ ] Should be able to load waveform whilst viewing it live.
        - could be quite challenging to implement for various reasons
