Describe the bug

The codeblocks (```) have too many newlines between lines

To Reproduce

Steps to reproduce the behavior:

1. Write a Markdown document with a code block
2. Execute the program to parse it to HTML
3. See error

Expected behavior

Not adding <br/> after each \n, because the <pre> tag already recognizes \n.

Additional context

Linked to this issue

When executing the program on the file test.md, you can observe that after the table, everything is considered as code.

Should be easy enough to fix...

Describe the bug

When you pipe a file into the program in the "read from stdin" mode (cat file.md | Markdown-CLI or Markdown-CLI -i file.md), it stops reading the stdin when a line is empty. This is because when reading from stdin normally (typing), it needs to stop reading at some moment. And it's programmed so that "the moment" is when you input a blank line.

To Reproduce

Steps to reproduce the behavior:

1. Create a non-empty file
2. Add a blank line in the middle of the file
3. Pipe the file into the program (cat file.md | Markdown-CLI)
4. See the problem

Expected behavior

Read to the end of the file that is being piped, while maintaining the functionality of reading from stdin by typing.

Additional context

This is a minor bug for the moment, also it is relatively easy to fix. It's a matter of knowin when to end reading from stdin.

Instead of wrapping the paragraphs, the current implementation just replaces the \n characters in the document for <br/> tags and calls it a day.
