Fix DECLARE statements in STORED PROCEDURES (#44)

[windiana42]

Copy DECLARE statements to subsequent statements only if they appear top level.
This fixes errors raised for

CREATE PROCEDURE CREATEALLDATES
    (
        @StartDate AS DATE, @EndDate AS DATE
    ) AS
    DECLARE @Current AS DATE = DATEADD(DD, 0, @StartDate); DROP TABLE IF EXISTS ##alldates CREATE TABLE ##alldates (
        dt DATE PRIMARY KEY
    ) WHILE @Current <= @EndDate BEGIN
    INSERT INTO ##alldates
    VALUES (@Current);
    SET @Current = DATEADD(DD, 1, @Current) -- add 1 to current day
END
GO
IF OBJECT_ID ( N'dbo.get_db_sampling_factor' , N'FN' ) IS NOT NULL DROP FUNCTION get_db_sampling_factor ;
GO

@SimeonStoykovQC do you expect this to be resolved by #56?
I still see the problem in pytsql 1.2.3.

I think this file is autogenerated from the ANTLR grammar and we shouldn't modify it manually

From what I remember, #56 and #59 just add things to the grammar, but no new functionality around it. Here it looks like you need to change our logic around it?

By the way, we try to be in sync with the ANTLR grammar (there is a CI job that syncs it regularly), so if you also want to push grammar changes, consider doing it upstream.
