Support js-output-optimization and remove-circulars in compilerOptions

[Harbs]

Hi Josh,

I'm really liking your extesion.

I'm not sure if I'm doing something wrong, but I tried adding the following items to compilerOptions in the asconfig.json file:
"js-output-optimization": "skipAsCoercions",
"remove-circulars": true,

I get "unknown compiler option" for both of those.

I'll get these added in a future version. When I release 0.1.1, you'll be able to add them to the new additionalOptions field in asconfig.json.

additionalOptions should be fine. Looking forward.

I just released version 0.1.1 of the extension. It now supports the additionalOptions field.
