feat(harper-core): Mark shebangs as unlintable

[sohunpatel]

Closes #65.

Changes

• Adds check to see if the content is a shebang, in the parse function.
• Add test to comment parser to make sure that comments with shebang are ignored

I am not sure if this is a great solution since this should only apply to comment parsers, but I could not find an elegant solution for that.

I think a better solution would be to mask them out in harper-tree-sitter. See fd5ebae.

@grantlemons, @sohunpatel I think the best way to do this would be to create a new implementaion of the Masker trait that ignores lines with shebangs. From there, it'd wrap it around the inner Masker that CommentParser uses internally.

Let me know if you have any questions about any of that.

[elijah-potter]

I may tackle this eventually, but it doesn't seem that this PR is getting more attention. Since it is still not in a satisfactory state, I'm going to close it.

Let me know if you have any questions about any of that.

@elijah-potter How strongly do you feel about this approach? I'm currently testing out a one-line change which modifies harper-comments/src/masker.rs and I think this would be a bit simpler than creating a new Masker implementation, but I suppose what you describe would have cleaner separation.

[elijah-potter]

@holman, that depends on what the one-line change looks like. Why don't you open a draft PR and we can take a look?
