Warn if "ORDER BY" is used on multiple columns and only *some* columns specify explicit ordering
See original GitHub issueWe had a bad bug recently in a project where somebody wrote this:
ORDER BY a, b DESC
They thought it meant this:
ORDER BY a DESC, b DESC
But it actually means this:
ORDER BY a ASC, b DESC
Suggestion: SQLFluff should warn that it’s “potentially ambiguous” if an ORDER BY specifies the order direction ASC or DESC on some but not all columns. An automatic fix for this would be to have SQLFluff add ASC to any columns that didn’t specify a sort order in the ORDER BY.

Hello! I’d like to try to take a stab at this. I really like sqlfluff. Niall said this would be a good first issue for me. I am hoping to carve out time this weekend to start on it if that’s okay.
@bdelamotte: Thank you so much for the code! This was the first time I’d worked on a lint rule that made fixes to the code, and your code got me 80% of the way to finished. 💯
