Doesn't compile on absent new line

[ureeves]

Describe the bug

When compiling a circuit that is missing a final new line an error is produced:

Error: Pest(Error { variant: ParsingError { positives: [sign], negatives: [] }, location: Pos(18), line_col: Pos((2, 9)), path: None, line: "c + d = e", continued_line: None })

To Reproduce

Fill a file with a small circuit - perhaps the simple equation a+b=c and "forget" to add a new line at the end of the file. The run:

plangc compile test.plang

Expected Behavior
It shouldn't be a problem when there is a new line at the end of the circuit description.
