Crash during scraping

[Sherlock92]

Thanks for the great library, just wanted to report a crash I came across:

Traceback (most recent call last):
  File "rpscrape.py", line 586, in <module>
    main()
  File "rpscrape.py", line 582, in main
    parse_args([arg.strip() for arg in args.split()])
  File "rpscrape.py", line 563, in parse_args
    scrape_races(races, course_name(scrape_target), args[1], code)
  File "rpscrape.py", line 488, in scrape_races
    times = calculate_times(win_time, btn, going, code, course_name)
  File "rpscrape.py", line 359, in calculate_times
    time = (win_time + (float(dist) / lps_scale))
UnboundLocalError: local variable 'lps_scale' referenced before assignment

Which I saw after running the script with these arguments: gb 1999-2019 flat

What was the last race in the recorded data

Looks like it was 1999-04-27,Bath,3:30,Tote Fillies' Stakes Showcase Handicap

I think it had been running for about half an hour leading up to it.

Had an idea as soon as I saw Bath that I had forgot to add the old going description 'hard'.

Fixed
