Bank Statement XLSX Import

This module extends the bank statement import feature so that Excel XLSX files can be used as a source for bank statements, in addition to the formats already supported by the base module.

When you use the bank statement import wizard and upload a file, Odoo now recognises the standard XLSX MIME type and routes it to the XLSX parser. The parser reads the active sheet of the workbook, applies the column mapping you configured (header row, skipped header lines, skipped footer lines, column offset), and converts each row into a statement line.

• Header handling: if the mapping says there is no header, no header row is read; otherwise the header row is taken after the configured number of skipped lines and after the column offset.
• Date handling: date cells found in the file are formatted using the timestamp format defined in the mapping, so they can be interpreted correctly.
• Row range: data rows are read between the header and the footer, respecting the configured skip counts.

Everything else — the import wizard, the mapping configuration, and the creation of statement lines — comes from the parent module account_statement_import_sheet_file. This module only adds the XLSX-specific reading logic on the model account.statement.import.sheet.parser.
