Support for 1.47

[Josh0Trucker]

When using ts-map with ETS2 1.47 some of the map overlays are incorrectly assigned. It looks like SCS has changed the bit positions/definitions of the map overlay flags (core_map_version: 898). In the values below byte 3 is on the left and byte 0 is on the right.

Here is how the flags were defined prior to 1.47:

0x0000_0001 = Hide for zoom level 0
0x0000_0002 = Hide for zoom level 1
0x0000_0004 = Hide for zoom level 2
0x0000_0008 = Hide for zoom level 3
0x0000_0010 = Hide for zoom level 4
0x0000_0020 = Hide for zoom level 5
0x0000_0040 = Hide for zoom level 6
0x0000_0080 = Hide for zoom level 7
0x0000_FF00 = DLC guard field
0x0001_0000 = Parking type
0x0002_0000 = City name type
0x0004_0000 = User text type
0x0008_0000 = Secret overlay
0x0010_0000 = Landmark type

And here is how the flags appear to be defined starting with 1.47:

0x0000_0007 = Type field:
  0x0000_0000 = Road
  0x0000_0001 = Parking
  0x0000_0002 = City name
  0x0000_0003 = User text
  0x0000_0004 = Landmark
0x0000_FF00 = DLC guard field
0x0001_0000 = Secret overlay
0x0002_0000 = Hide for zoom level 0
0x0004_0000 = Hide for zoom level 1
0x0008_0000 = Hide for zoom level 2
0x0010_0000 = Hide for zoom level 3
0x0020_0000 = Hide for zoom level 4
0x0040_0000 = Hide for zoom level 5
0x0080_0000 = Hide for zoom level 6
0x0100_0000 = Hide for zoom level 7

Wow, thanks for the research Josh.
Had not looked into 1.47 yet and seems like that was the only change (for now at least).
So easy update for me thanks to you :)
