Data_dly gear not compiling

[Risto97]

https://github.com/Risto97/pygears_issues/blob/master/data_dly/run_test.py Verilator fails to compile data_dly gear because of missing dreg.sv.

I see 3 ways for resolving this. -Append dreg verilog module in data_dly.sv file (simplest).

-Generate dreg gear modules in loop like in data_dly2(), this is not optimal because of multiple dreg.sv files generated. Also python fails with recursion error for more than 1000 instances (maybe a seperate issue).

-Try implement it in hls.
