Code Outline with unformatted JSON, high CPU

[JayNaire]

Just an observation, (file under FYI) :

Opening a JSON "log" file (about 200kB, rough format below) that doesn't contain any formatting / newlines incurs 100% CPU time for about 13 minutes. The code outline then appears correctly and all is well.

Formatting the document, saving and reopening results in no hogging and a delay of just 2 seconds or less before the outline appears.

Whether the hog is from native vscode json or Code Outline I know not.
code --status says
CPU% is 100% for extensionHost when hogging occurs
CPU% is 0% for electron_node jsonServerMain.js

FWIW: JSON format:

{
"roomTemperatures": {
"Room1": [
{
"x": "2018-02-16T12:45:47.623Z",
"y": 20.3
},
...another 500 data points
],
...another 13 rooms
}

Code Outline does not do any document parsing on its own and relies on the SymbolProvider API to be implemented by specific language extensions. I believe the JSON one is built into VS Code itself.
