Fix KeyError when passing an unrecognized string type to create_table or add_column

Browse source 
Passing a valid SQLite type string that is not in COLUMN_TYPE_MAPPING, such as
NUMERIC or ANY, raised KeyError instead of being used as-is. The fix falls back
to the raw string value when the type is a string not present in the mapping,
matching the documented behaviour: col_type accepts Python types or SQLite type
strings.
