py-sqlalchemy: updated to 1.2.2

1.2.2:
orm
[orm] [bug] Fixed 1.2 regression regarding new bulk_replace event where a \ 
backref would fail to remove an object from the previous owner when a \ 
bulk-assignment assigned the object to a new owner.

mysql
[mysql] [bug] Added more MySQL 8.0 reserved words to the MySQL dialect for \ 
quoting purposes. Pull request courtesy Riccardo Magliocchetti.

mssql
[mssql] [bug] Added ODBC error code 10054 to the list of error codes that count \ 
as a disconnect for ODBC / MSSQL server.

oracle
[oracle] [bug] The cx_Oracle dialect now calls setinputsizes() with \ 
cx_Oracle.NCHAR unconditionally when the NVARCHAR2 datatype, in SQLAlchemy \ 
corresponding to sqltypes.Unicode(), is in use. Per cx_Oracle’s author this \ 
allows the correct conversions to occur within the Oracle client regardless of \ 
the setting for NLS_NCHAR_CHARACTERSET.
