[FEATURE] [Formatter] Single-line nested blocks are broken up

[GergelyKalmar]

Issue

It seems that DjLint currently breaks up single-line nested blocks into multiple lines which inserts meaningful whitespace in HTML templates.

How To Reproduce

Create a file called html.j with the following contents:

{% block title %}{% block subtitle %}{% endblock %} | example{% endblock %}

Run DJLint as follows:

$ djlint --check test.html.j --indent 2 --profile jinja
Checking 1/1 files

test.html.j
---
@@ -1 +1,4 @@

-{% block title %}{% block subtitle %}{% endblock %} | example{% endblock %}
+{% block title %}
+  {% block subtitle %}{% endblock %}
+  | example
+{% endblock %}

1 file would be updated.

I understand that the issue can be mitigated with whitespace control, however, in some cases it would be preferable if simple nested blocks are kept untouched. Perhaps a command-line option would be useful that lets such blocks be preserved.

Currently, these tags are all broken out onto multiple lines. You may take a look at the djhtml package which will only add indentation to your html.
