Fuzzing

cargo +nightly fuzz run xlsx fuzz/corpus/xlsx fuzz/seeds/xlsx

fuzz/seeds/ holds checked-in starting inputs; fuzz/corpus/ is the working directory libfuzzer writes to and is not checked in.

xls, xlsb and numfmt wrap their input in a valid container (an OLE compound file, an OPC package, a styles part) so mutation reaches the record and format-code parsers rather than dying at the container gate. xlsx takes a whole workbook, and its seeds cover all three containers because the frontend picks the reader from the bytes.
