Windows line endings cause IndexOutOfRange during tokenization
I am parsing view and stored procedure definitions from windows-based mssql.

I am getting failures from IndexOutOfRange and strange parsing contexts where the leading character has been removed.

I think I have identified the problem + solution - are you open to a PR (with unit test)?

The issue is this:

In _advance:
https://github.com/tobymao/sqlglot/blob/a18444dbd7ccfc05b189dcb2005c85a1048cc8de/sqlglot/tokens.py#L1008

If it sees \r\n, then it sets i to 2
_current is increased by i
_char always looks at position _current-1

This can lead to it looking past the end of the source text, as _current-1 > size

I believe the fix is something like changing:
https://github.com/tobymao/sqlglot/blob/a18444dbd7ccfc05b189dcb2005c85a1048cc8de/sqlglot/tokens.py#L1022

to

```
        if self._end:
            self._peek = ""
            self._char = self.sql[self.size - 1]
        else:
            self._char = self.sql[self._current - 1]
            self._peek = self.sql[self._current]
```
