Bug when Getting column lineage on Teradata with intermediate tables

[Ricardop1]

Describe the bug
Relations are wrong when using intermediate tables on column level. When using a intermediate table and naming its columns, it is describing the columns as the Table/Subquery instead of the table name specified.

SQL

insert into db_test.table_target
select col_1_renamed, col_2_renamed from
(Select col1, max(col2) from db_test.table_src
where
  col1 = "AV" and
  col2 is not null
) AS Inter_table(col_1_renamed, col_2_renamed);

To Reproduce

from sqllineage.runner import LineageRunner, LineageLevel

query = """ insert into db_test.table_target
select col_1_renamed, col_2_renamed from
(Select col1, max(col2) from db_test.table_src
where
  col1 = "AV" and
  col2 is not null
) AS Inter_table(col_1_renamed, col_2_renamed);
"""
result = (
    LineageRunner(query, dialect="teradata")
)
lineage_stmt = result.to_cytoscape(LineageLevel.COLUMN)
print(lineage_stmt)

{'data': {'id': 'e3', 'source': '(col_1_renamed, col_2_renamed).col_2_renamed', 'target': 'db_test.table_target.col_2_renamed'}}

Expected behavior
The code should detect Inter_table as the Subquery and not (col_1_renamed, col_2_renamed) as a whole. The column lineage as source and target should be:
db_test.table_src.col1 -> Inter_table.col_1_renamed
db_test.table_src.col2 -> Inter_table.col_2_renamed

Inter_table.col_1_renamed -> db_test.table_target.col_1_renamed
Inter_table.col_2_renamed -> db_test.table_target.col_2_renamed

Additional context
Looks like there is a problem when detecting intermediate tables
