Noticed in YumblTV's video about Parclo's ( https://www.youtube.com/watch?v=czfrH-HRiXg&t=618s ) that some of the chevrons (markings) were pointing in the wrong direction. This is adjusted.

Applied the following TM:PE settngs to all A2021 interchanges:

- Lane connections
- Adjusted speed limits where necessary
- Removed crosswalks where necessary
- Allowed 'through movement' where necessary

TM:PE is not necessary to load and place the interchanges. But without it, you do not get the above mentioned features.
