Attempt to Improve Reliability

Have pip directly download and install backup GPTQ wheel instead of first downloading through curl.
Install bitsandbytes from wheel compiled for Windows from modified source.
Add clarification of minor, intermittent issue to instructions.
Add system32 folder to end of PATH rather than beginning.
Add warning when installed under a path containing spaces.
