* Change reset strategy in ariane_verilog_wrap.sv, remove unneeded sigs in serpent_peripherals.
* saving...
* ⬆️ Updates for new FPU
* Add sv fpu to FPGA flow
* Use multi-threading capabilities of verilator
- Deactivate non-standard floating point arguments
- Make multi-threading conditional on the availability of verilator 4
* Remove DPI threadsafety
* Reduce FPGA clock frequency
- Remove couple of -v- tests to reduce test-time
* Fix documentation and fpga flow
