overwites configured editor indentation

[iconecd]

why do the configurable settings angular-template-formatter.indentWidth and/ angular-template-formatter.useSpaces when vscode includes the settings editor.tabSize and editor.insertSpaces ?

my templates are being reformatted by default to a style inconsistent with my team's style rules, and the existence of these settings rather than the usage of editor/workspace/user settings caused me to hunt down the reason.

if you need a PR to fix this, i'll write it.
