Indentation of tsconfig is inconsistent with Atom-generated file

[texel]

Great extension! One issue I'm running into is that Atom is rewriting the .tsconfig file using 4-space indentation, and tsconfig-glob seems to have 2 spaces hard coded. It would be great if instead, it detected the indentation style of the existing file, and used that on rewrite.

Hi, thanks! That was good idea, but I'm not sure I can add this feature in the near future. Any PR may welcome :)
