Changed parser mode to 'codemod'

[initram]

This allows the linter to lint indentation correctly even if the line starts with  

Fixes #120

Though some changes were needed to rules that work on TextNodes as they now behave slightly different. The changes I made to the block indentation rule also made it a bit more consistent in my opinion.

Additional test may be needed to cover what ever corners cases there may be, but all current tests should pass.

Thanks for working on this!

I am concerned that this is effectively a breaking change for rules like no-bare-strings (because the whitelist/blacklist there are specifically relying on the fact that the tokens have been swapped). I still think we should do this change, just need to think through how it may be considered a breaking bugfix.

👍I absolutely had this package in mind when adding this feature upstream.

Yes, If people had a "&" in their white list and "&" in their template, then it would break for them after this change. But any rule change or fix, may break someones flow.
Also people who have had   in their templates will now get warnings, as this was mapped to whitespace, but it no longer is. We could consider adding more items the the default white list and test that it works for string that are currently being transformed into whitespace.

Right, I think the main thing we need to ensure is that the items in the current default whitelist that could have been converted from an HTML entity have a corresponding whitelist entry for the entity as well.

@initram - Would you mind rebasing? There have been changes to lib/index.js which are causing conflicts, but also the definition of codemod mode changed in @glimmer/syntax@0.43.0 (see glimmerjs/glimmer-vm#983 for details on that breakage WRT codemod mode). We may need more tweaks to accommodate those changes.

I went ahead and rebased for you, looks like no additional failures crop up so this is good to land!

Thank you again @initram!
