Write a error message parser script in JS

[rep-movsd]

Take an input file like:
../seephit.h:704:7: in constexpr expansion of 'ParseError(((const char*)"Mismatched Close Tag")).ErrLine::operator[](((size_t)iLine))'
invalid_missing_tag.spt:1:1: error: array subscript value '4' is outside the bounds of array type 'int [0]'

And output Mismatched Close Tag at line: 4
