Added new features and optimization [READ EXTENDED DESCRIPTION] (#39)

* [READ EXTENDED DESCRIPTION]

Changes made:
1. Removed a few print statements for a bit less cluttering (Makes debugging a bit harder)

3. Added an IMPORT command for running external ".dd" files.
4. Added an LED command that toggles the builtin LED.

* Updated the DELETE keycode
