Support creating unsigned int types from SQL

[Ted-Jiang]

From apache/datafusion#3146 (comment)

We should support creating unsigned int types from SQL.

For now seems all int are signed

❯ select 1;
+----------+
| Int64(1) |
+----------+
| 1        |
+----------+
1 row in set. Query took 0.004 seconds.
❯ select 10000;
+--------------+
| Int64(10000) |
+--------------+
| 10000        |
+--------------+
1 row in set. Query took 0.002 seconds.
❯ select -1;
+-----------+
| Int64(-1) |
+-----------+
| -1        |
+-----------+
1 row in set. Query took 0.001 seconds.

@alamb @Ted-Jiang isn't that fixed since #428?

I can't see what's the problem
