Title: changes to bitburner driver for bitburner fury boards

Justification of the changes:
- Bitburner boards do not contain a real USB-to-serial chip, so the send delays are unnecessary and will limit the hashrate of large and/or powerful stacks.
- The valid range for core voltage and number of miners was widened to accommodate Bitfury-based boards.
