feat: skip UTF-8 BOM in source input and add regression test

Add handling for UTF-8 byte order mark (BOM) at the start of source code
in wrenCompile function by checking for the three-byte sequence \xEF\xBB\xBF
and advancing the source pointer past it. Include a regression test file
(test/regression/520.wren) that contains a BOM to verify the fix works
correctly.
