PyDBML fails to parse Indexes with names

[pierresouchay]

While working on https://github.com/holistics/dbml/pull/549

I discovered that PyDBML seems to fail if name is set on an index, here is a minimum example:

Table "alembic_version" {
  "version_num" "character varying(32)" [pk, not null]

Indexes {
  version_num [pk, name: 'alembic_version_pk']
}
}

According to the specification, the value name name: 'alembic_version_pk' should be used to set a name to the index if I am not mistaken

Here, it fails with the following error:
