The form for configuring the 'sheet_name' and the 'no_headers' values are not visible on either the Feed Type or Feed form interfaces.
This is preventing specific sheets from being targeted, limiting the utility of the module to the first sheet.
Visiting:
/admin/structure/feeds/add
/feed/*/edit?destination=/admin/content/feed
Cannot see "Sheet name' textfield.
Cannot see 'No Headers' checkbox.
Update src/Feeds/Parser/XlsxParser.php to target \feeds_xlsx\Feeds\Parser\Form\ directory rather than \feeds\Feeds\Parser\Form.
