Parser(sql_text).columns brought the CPU high load problem

[lytum]

I used sql_metadata to extract columns of sql text, version is "2.6.0"
But gradually I found this library brought a big issue, as shown in the figure below.

Anyone has met the same problem and know how to solve this question?

@lytum - can you provide the SQL query that causes that high CPU usage?

It can be a similar issue to #556.
