XLSX no longer processing due to xlrd

So it looks like the dependency `messytables` uses `xlrd` for excel file processing. The latest `xlrd` does not support XLSX files anymore due to, as I understand it, security concerns. `messytables` appears to be a dead project, not having had any activity in the last 2 years. This [stack overflow post](https://stackoverflow.com/questions/65254535/xlrd-biffh-xlrderror-excel-xlsx-file-not-supported) says that `xlrd` should be swapped out for `openpyxl`, but with `messytables` being unmaintained, that seems unlikely to happen. Is there any effort being taken to support XLSX files?
