Add support for ignore_not_found=true parameter in document.delete()

[philippemilink]

The documentation of the method to delete a single document states:

NOTE: When a document does not exist for the given id, an error is returned. To ignore this error and treat the deletion as success, you can send ignore_not_found=true parameter.

However, calling

client.collections['companies'].documents['124'].delete(ignore_not_found=True)

raises an exception: TypeError: Document.delete() got an unexpected keyword argument 'ignore_not_found'.

Could you add the support of this parameter, please?

EDIT: actually, this would also be needed for the delete by query function:

client.collections['companies'].documents.delete({'filter_by': 'num_employees:>100'})

because now it raises a typesense.exceptions.ObjectNotFound exception.
