Improve error handling

[simplenotezy]

I think the library needs better error handling. I've often been stuck for quite a while with simple queries that fail with an unknown rust error.

Now I am facing this one, and I am not sure why:

thread 'main' panicked at src/ts_generator/sql_parser/expressions/translate_expr.rs:189:59:
called `Option::unwrap()` on a `None` value

With this code:

  const usersQuery = await dataSource.query({
    text: sql`
  SELECT
    u.name
  FROM
    "user" u
  WHERE
    u.id = ANY($1)
`,
    values: [ids],
  });

p.s. Impressive how fast you progress with this package, good job!

For some reason this fixes the error:

  const usersQuery = await dataSource.query({
    text: sql`
  SELECT
+    name::string AS "name"
-    name
  FROM
    "user"
  WHERE
    id = ANY($1)
`,
    values: [ids],
  });

Separate to this particular problem, I've improved error message handlings in several areas including DB connection issues https://github.com/JasonShin/sqlx-ts/pull/156/files
