Small fixes for Zandvoort 2020 v2.27-fix

This is my first proper upload, so please be nice, thanks.

Zandvoort_2020 2.27 is now required! If for some reason you don't have it, you can subscribe to it here.

Anyway, I can contribute a bit for once - these are small fixes for the Zandvoort 2020 layout, which was released originally on May 3rd for rFactor 2. This is mainly intended for offline usage (hotlapping or racing against AI).
There are 3 versions available:

• Race Distance fix. Originally, it is set to a whooping 90 Laps. That was corrected - official distance is 72 Laps. (Mostly affects those who run "% Laps" rather than a set number of laps.) No other changes are included.
• DRS Zones fix. Zones were already set in the game, however, one line missing means that they were only available in the race. Fixed by adding "RearFlapZoneSessions=31". Race Distance fix is also included.
  (To explain - by default, DRS zones work in the game in a pre-2013 ruleset - DRS works anywhere on the track in any session, except race, where it works only in DRS zones. This fixes the ruleset to represent current DRS usage rules - as currently DRS is only available in the DRS zones at all times.)
• F1 2020 fix. This version aims to represent actual F1 2020 race more closely by representing actual Session Times and Lengths (or at least what should have been). DRS Zones fix and Race Distance fix are also included.

How to install:

1. Select the version you want to install. You can only choose one.
2. Place the selected .rfcmp in the Packages folder and install it.
3. That's it - now the updated version is available for use offline. (NOTE: You should still be able to use the older version offline, however, to access it, you will need to either uninstall the fix or make a Mod Package with the original version.)

Enjoy, and let me know if you have any issues! (Hopefully you shouldn't.)
Remember - this won't work after a new Zandvoort update from S397.
