overwites configured editor indentation #10

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.
