Revolut importer is missing meta field when returning a balance

[kosli]

I have problems using the Revolut importer with https://github.com/jbms/beancount-import
If the Revolut importer returns a balance, it is not providing the meta field and so beancount-import fails due to the missing filename.

beancounttools/src/tariochbctools/importers/revolut/importer.py

Line 80 in 5ae47a5

entry = data.Balance(meta, book_date, self.account, balance, None, None)

The importer should have the meta variable set too, like it does for transactions:

beancounttools/src/tariochbctools/importers/revolut/importer.py

Line 62 in 5ae47a5

meta = data.new_metadata(file.name, 0, metakv)

At least the sample importers of beancount are providing the meta with balance entries too:
https://github.com/beancount/beancount/tree/v2/beancount/ingest/importers/

I'll try to test and submit a PR later on.

Thanks @tarioch Works like a charm now.
