Feature: Add configuration for tabs vs spaces

thats kind of a bummer especially considering that my VSCode setting for that very file was 4 spaces, rather than tabs. Yet, when auto-formatting from this extension kicked in, it added a TAB instead.

for one, it's unfortunate that vscode settings were ignored but also, when saving tabs in SFMC, they are regularly just removed.

please add configuration options similar to eslint or prettier for this:

• prettier:
  • https://prettier.io/docs/en/options.html#tab-width
  • https://prettier.io/docs/en/options.html#tabs

you've already added the feature that it automatically looks into what is set in vscode so I'd say this one is not a high priority

This should already work based on VSCode settings (as you've mentioned in the previous comment).
You mean to have a separate settings in the Preferences for the extension? Or in another way?
