Issues with types in DWG -> JSON -> DWG conversion

[michal-josef-spacek]

I found two issues with conversion:

2384c2384
<     "minus_1": 4294967295,
---
>     "minus_1": 2147483647,

8421c8421
<           4278190080
---
>           2147483647

which is XRECORD xdata item

...
        [
          102,
          "RTVSPost2010Prop51ColorRGB"
        ],
        [
          90, 
          2147483647
        ],
...

dwgread of them:

  xdata[99] type: 90 [RS]
xdata[99]: -16777216 [RL 90]
  xdata[100] type: 102 [RS]

and

xdata[98]: "RTVSPost2010Prop51ColorRGB" [TV 102]
  xdata[99] type: 90 [RS]
xdata[99]: 2147483647 [RL 90]
  xdata[100] type: 102 [RS]

I prepared fix for 1), but I don't see where is issue for 2)

Still issue 2)

Testing file: Circle_Original.dwg.gz
Testing environment: Windows (tested on mingw version)

Structure (via dwgread):

xdata[98]: "RTVSPost2010Prop51ColorRGB" [TV 102]
  xdata[99] type: 90 [RS]
xdata[99]: -16777216 [RL 90]
  xdata[100] type: 102 [RS]

is in DXF:

102
RTVSPost2010Prop51ColorRGB
 90
-16777216

and JSON:

        [
          102,
          "RTVSPost2010Prop51ColorRGB"
        ],
        [
          90,
          4278190080
        ],

This means, that conversion from DWG to JSON is wrong.

btw: Conversion to DXF via LibreDWG dwg2dxf.exe is fine.

102
RTVSPost2010Prop51ColorRGB
 90
-16777216

Conversion from DWG to JSON is bad in Windows and Linux too (-16777216 → 4278190080).

Conversion on Linux is -16777216 →-16777216, but on Windows still -16777216 → 4278190080.
