Metadata doesn't get passed to children entities making it impossible to combine search and filter for table entities

[brrttwrks]

When tables are created from workbooks during ingest, the metadata of the workbook isn't passed to the tables, and therefore it is not possible to search by keyword and then use the filters on the metadata of the document.

It would be great if the metadata was passed on to children entities in this case. This might also be applicable to Pages/Page entities.

For Page entities, all metadata needs to be added to the followthemoney schema first.

I'm currently working on getting the metadata into Table entities.
