Changes Made:

• Updated consecutive blank lines to consider a line to be empty if it is solely whitespace

• Added ability to ignore footnotes after a task for moving footnote to after punctuation
• Updated table regex to make sure it does not end with a new line character in order to help fix some issues with new lines around it
