fix: missing time type

[maltoze]

Currently, Executing this sql will throw exception.

SELECT CURTIME() AS result

File "<string>", line 1, in <module> File "/home/maltoze/repos/superset/venv/lib/python3.7/site-packages/es/baseapi.py", line 37, in wrap return f(self, *args, **kwargs) File "/home/maltoze/repos/superset/venv/lib/python3.7/site-packages/es/elastic/api.py", line 145, in execute self.description = get_description_from_columns(columns) File "/home/maltoze/repos/superset/venv/lib/python3.7/site-packages/es/baseapi.py", line 105, in get_description_from_columns for column in columns File "/home/maltoze/repos/superset/venv/lib/python3.7/site-packages/es/baseapi.py", line 105, in <listcomp> for column in columns File "/home/maltoze/repos/superset/venv/lib/python3.7/site-packages/es/baseapi.py", line 87, in get_type return type_map[data_type.lower()] KeyError: 'time' 

This will fix it.
