Simple-ddl-parser

Fixes:

1. Fix for issue with 'at time zone' https://github.com/xnuinside/simple-ddl-parser/issues/112

New features:

1. Added flag to raise errors if parser cannot parse statement DDLParser(.., silent=False) - https://github.com/xnuinside/simple-ddl-parser/issues/109
2. Added flag to DDLParser(.., normalize_names=True) that change output of parser:
if flag is True (default 'False') then all identifiers will be returned without '[', '"' and other delimiters that used in different SQL dialects to separate custom names from reserved words & statements.
For example, if flag set 'True' and you pass this input:

CREATE TABLE [dbo].[TO_Requests](
[Request_ID] [int] IDENTITY(1,1) NOT NULL,
[user_id] [int]

In output you will have names like 'dbo' and 'TO_Requests', not '[dbo]' and '[TO_Requests]'.
