[Bug] Missing traceback line hinting

[Luna-Klatzer]

• I have read the documentation

This issue exists in the latest version

• I am using the latest version

Current Behavior

When compiling a program errors are only thrown with their line, column and exception name, but they do not contain any line of code displaying the origin of the error.

Example:

var x: num = 4; 
var x: num = 5;

Traceback:

Traceback:
  File 'anonymous-script', line 2, col 0:    
InvalidOverwriteError: Definition of variable 'x' already exists. May not overwrite existing definitions.

Expected Behavior

The traceback should contain the original line of the error.

Expected traceback:

Traceback:
  File 'anonymous-script', line 2, col 0:    
    var x: num = 5;
    ^^^^^^^^^^^^^^^
InvalidOverwriteError: Definition of variable 'x' already exists. May not overwrite existing definitions.

Steps To Reproduce

1. Compile a program using KipperCompiler.compile() or KipperProgramContext.compileProgram() with invalid code.
2. Get exception using try { } catch (e) {}
3. Fetch traceback using e.getTraceback()

Environment

• Kipper: v0.3.0
• Operating System (+ Version): Windows 10 - 19043.1645
