Issue: FR: Obsidian Comment %% Has Empty Lines Added Around It
I have the following section:

```
%%
due-date:: [[2022-06-10]]
%%
```

which gets linted as follows -- the result is not expected or wanted:

```
%%

due-date:: [[2022-06-10]]

%%
```

It would be great if ` Linter ` would respect the comments' styling.

Thank you for considering.
Pull request description: Ignore Multiline Obsidian Comments for Paragraph Modifications
Fixes #223 

Made sure that multiline obsidian comments are treated as such for purposes of paragraph rules, specifically two spaces at the end of lines with content around it and blank lines around each paragraph.

Changes Made:
- Added a function for ignoring multiline obsidian comments
- Updated the two paragraph rules to ignore multiline obsidian comments
- Added tests for multiline comments
- Fixed tests pointed out by #264 to use the proper values
