Miden Assembly Code Formatter

This is a very basic Miden Assembly code formatter.

Basic Rules this formatter follows:

1. It indents using 4 spaces when it encounters: begin, if, else, proc, export, repeat, while, end.
2. It removes trailing spaces
3. It deletes lines with more than 2 empty spaces

That's pretty much it.

Would be cool to auto format comments, and maybe some other things.
