visit mechanism for BYTEINT

[sandan]

Here's a reprex:

Suppose there is a table:

create table byteint_t(i byteint);

mytable = Table("byteint_t", meta, autoload=True, autoload_with=td_engine)
col = mytable.c
print(col.i.type)

Error:
sqlalchemy.exc.UnsupportedCompilationError: Compiler <sqlalchemy.sql.compiler.GenericTypeCompiler object at 0x1081bbcc0> can't render element of type <class 'sqlalchemy_teradata.types.BYTEINT'>
