Fix: Handle "/" character in query names to prevent NotFoundError

[mkohei]

Summary

This pull request fixes the NotFoundError that occurs when query names contain the "/" character.

Details

As reported in the issue #106, query names with the "/" character were not being properly encoded, leading to an API endpoint not found error. The issue was due to the default behavior of the urllib.parse.quote function, which does not encode the "/" character.

Fix

Updated the create_url function in tdclient/util.py as follows:

-    quoted_values = {k: urlquote(str(v)) for k, v in values.items()}
+    quoted_values = {k: urlquote(str(v), safe="") for k, v in values.items()}

This change ensures that all characters, including "/", are correctly encoded.

@mkohei Overall, looks good. Can you add a unit test for it?
